P0601 Fault Code: Understanding The Causes And Solutions

The P0601 fault code refers to a problem with the Control Module Read Only Memory (ROM). The Engine Control Module (ECM) uses an electrically erasable programmable read-only memory (EEPROM) to store program information and calibrations for engine and trans-axle diagnostics. The ECM also uses a checksum, which is a value calculated by adding up all the numbers in the software, to detect errors in the software.

If the values recorded by the ECM and the checksum do not match, a checksum error is indicated by the P0601 fault code.

This code alerts the driver through the Malfunction Indicator Lamp (MIL) and helps the technician identify and repair the likely problem-making parts.

If you’re seeing the P0601 fault code with the engine light on, it could be due to a faulty Engine Control Module (ECM), an open or shorted ECM harness, a poor electrical connection in the ECM circuit, or low battery voltage. To visually inspect these possible causes, check the wiring harness and connectors related to the ECM. Look for any damaged components and examine the connector’s pins for any signs of being broken, bent, pushed out, or corroded.

If you notice the Engine Light ON or the Service Engine Soon Warning Light, it could be due to a faulty Engine Control Module (ECM). This can be caused by an open or shorted ECM harness, poor electrical connection in the ECM circuit, or low battery voltage. To address this issue, you can start by visually inspecting the wiring harness and connectors. Look for any damaged components and check for broken, bent, pushed out, or corroded connector pins. It’s also important to check the possible causes mentioned above.

When troubleshooting the P0601 fault code, it is crucial to check for damaged components and inspect the wiring harness and connectors. This is because a faulty Engine Control Module (ECM), open or shorted ECM harness, poor electrical connection in the ECM circuit, or low battery voltage can trigger this code. By visually inspecting the wiring harness and connectors, you can identify any broken, bent, pushed out, or corroded pins that may be causing the issue. This step is essential in finding the root cause and ensuring a proper fix.

If your engine light is on and you’re seeing the P0601 fault code, it’s likely due to a faulty Engine Control Module (ECM). To fix it, start by visually inspecting the wiring harness and connectors. Look for any damage or corrosion.

Check for broken or bent pins on the connectors.

Don’t forget to check the battery voltage too.

• Get Help with P0601

OBD II fault code P0601 is defined as “Internal Control Module Memory Check Sum Error”, and is set when the PCM (Powertrain Control Module) detects either a breakdown in communication between itself and one or more supporting control modules, or between two or more supporting control modules. In all cases, the PCM acts as the central or main controller.

When a breakdown in communication occurs in any area of the CAN system, a code will be stored and a warning light will be triggered. However, depending on the application, several drive cycles (up to 8 in some cases) may be required to before a code is stored and a warning light is triggered.

The CAN (Controller Area Network) typically includes control modules for systems such as, turbo boost control, ABS brakes, the instrument panel, anti-theft/security system, cruise control, fuel management, transmission control, climate control, proximity control, body control, and safety systems such as traction and stability control. Note that this list is not exhaustive, and that the actual number of control modules that make up the CAN system is make and model specific.

In practice, the CAN system monitors and controls every aspect of a vehicle’s operation by means of a system that allows all the microprocessors and controllers in a vehicle to constantly exchange messages and signals between themselves, and the sensors/systems they control. This is accomplished by the complex interconnection of all affected wiring harnesses to create a “distribution pipeline” to carry input and signal voltages from, and to various sensors, components, systems, other controllers, and ultimately to and from the PCM.

To illustrate how the system works (albeit in a grossly over simplified manner), imagine that the PCM receives a signal from the vehicle speed sensor. Provided that the signal is valid and that the CAN system is in good working order, the PCM will make the signal available to the-

• cruise control system (if fitted) for speed control purposes,
• ABS brakes system, which will compare the signal and the actual vehicle speed to information collected from the wheel speed sensors to arm the brake, stability and traction control systems,
• fuel management system via the throttle position sensor (and others) for the purposes of calculating an appropriate fuel delivery strategy,
• transmission control system to regulate efficient shifting,
• and the proximity warning system, among others.

NOTE: The above example of CAN bus operation is not definitive, and is meant for general informational purposes only. It should therefore NOT be used in any diagnostic procedure relating to the CAN bus system.

The image below shows a simplified approximation of which systems on a modern vehicle are interconnected by the Controller Area Network. Note that only critical systems are shown in this image. Other, non-critical like audio, GPS, lighting, security/anti-theft, and others are not shown.

The number of possible causes of P0601 is almost directly proportional to the complexity of the CAN bus system. Nonetheless, some causes occur more often than others, with the following being the most likely-

• Damaged, burnt, shorted, or corroded wiring and connectors.
• Open circuits.
• Poor controller ground connections.
• Defective drivers in one or more controllers.
• Defective electronic components in controllers.
• Damage to controllers caused by voltage spikes or low battery voltages.
• Short circuits caused by water ingress during flooding events.
• Unlike most other codes, a defective PCM is a distinct possibility with code P0601.

In some cases there may be no symptoms present other than a stored trouble code and an illuminated warning light. However, where drivability issues are present, the symptoms are almost always make and model specific. Typical symptoms could include the following-

• Harsh, erratic, or unpredictable shifting.
• Reduced fuel economy.
• Surging or hesitation upon acceleration.
• Poor acceleration and loss of power.
• Frequent engine stalling.
• Hard starting.
• Rough or erratic idling.
• Illuminated warning lights for the ABS, traction control, stability control, air bags, or collision warning systems. Note that not all these warning lights will always be illuminated on all applications.

NOTE: On applications that require multiple drive/fault cycles before a warning light illuminates, but code P0601 is stored, the code should NOT be ignored. In these cases, the code is pending, and it may illuminate one or more warning lights at any time.

WARNING #1: Due to the extreme complexity of the CAN bus system, non-professionals should ideally NOT attempt to diagnose and repair any codes that relate to this system. Some applications have up to 18 or more controllers that are interconnected with literally hundreds of circuits that share several thousand individual connections and connector pins. Moreover, generic code readers are NOT able to even indicate an area of the system in which a fault might be present, and even though specialized diagnostic equipment is available that can isolate certain parts of the CAN bus system, using this functionality to best effect requires expert knowledge and exceptional diagnostic skills. For instance, one accidental contact with a probe on an incorrect connector pin at the wrong time can destroy the memory on one or more controllers that may, or may not be reprogrammable.

Note that even specialists usually require anything from 40 to 50 hours (or more in some cases) to trace a fault in the CAN bus system, which makes this process extremely expensive, and even then there are no guarantees that the root cause of the problem will ever be found and repaired.  

WARNING #2: Even if you are confident that your diagnostic abilities and knowledge of automotive electronics are up to this mammoth endeavor, we do NOT recommend the use of generic code readers and multimeters to diagnose this code. At the very least, you need a scanner that can communicate with the CAN system via protocols such as SAE J1939 , GMLAN , OBD II, SAE J1587 and LIN , since these protocols determine the manner in which data in the system is received, formatted, and transmitted, as opposed to how fast  the data is transmitted. If you do not have access this class of diagnostic equipment, refer the vehicle for professional diagnosis and repair.

Warning #3: Note that diagnosing this code will require the disconnection of some or all controllers from the PCM, an action that could cause one or more controllers to lose their memory or programming. To prevent this, an approved memory saving device MUST be used in accordance with the instructions given in the manual.

Assuming that suitable diagnostic equipment is available, record all fault codes present as well as all available freeze frame data. This information can be crucially important in determining the order in which codes were generated and stored.

NOTE: When diagnosing code P0601 and there are other codes present such as those relating to misfires, rich/lean exhaust issues, fuel injection problems, transmission trouble, or almost any other driveability-related code, it is important to recognize that these codes are almost certainly the result of a communication failure in the CAN bus system, rather than indicators of problems in the systems to which the codes relate.

Therefore, always follow the rule that says codes must be diagnosed and repaired in the order in which they were stored. Thus, if code P0601 occurred first, it will be stored first, meaning that resolving P0601 will usually resolve all the other codes as well. Freeze frame data is the best tool to determine which code came first- P0601, or the host of other possible codes.

Perform a thorough visual inspection of all points where wiring terminates against the body work. These points are ground connections, and it is common to find loose connections, or even ground straps hanging loose after unrelated repairs had been done. Consult the manual on the locations of all ground connections, and ensure that all connections are tight and secure.

If poor ground connections were found and repaired, clear all codes, and rescan the system to see if any codes return. In some cases, it is possible that some controllers may need to be reintegrated or even reprogrammed after a communication failure. Consult the manual on the correct procedures for doing this.

NOTE: Many, if not most controllers have external ground connections that need to be secure for the controllers to work.

If all ground connections are secure, perform a thorough visual inspection of all wiring on the vehicle. Note that this inspection may require removal of the dashboard, seats, carpets, and even trim panels to gain access to all wiring harnesses.

Look for obvious signs of damaged, burnt, shorted, or corroded wiring and/or connectors. Be aware though that some kinds of damage may not be visible without removing all of the insulating material wrapped around the wiring harness(es). However, use extreme caution when removing insulation to prevent creating damage where there was none before.

If any damage is found, resist the temptation to repair wiring to prevent continuity, resistance, and other issues caused by poorly executed repairs. In these cases, the better option is always to replace the affected section of the harness with an OEM replacement.

Clear all codes, and rescan the system after replacing wiring to see if any codes return. In some cases, it is possible that some controllers may need to be reintegrated or even reprogrammed after a communication failure. Consult the manual on the correct procedures for doing this.

If no damage to the wiring is found but the code(s) persist despite performing the above steps, one option may be to replace the entire electrical harness with an OEM replacement. However, this is not guaranteed to resolve the problem, since the issue may be with a controller.

Typical problems with controllers include defective drivers, “memory loss”, and/or blown components due to any number of causes. For this reason, we do NOT recommend replacing the entire harness until exhaustive diagnostic tests had been performed on all controllers, including the PCM where this is possible.

NOTE: It is worth pointing out again that no code reader, regardless of its level of sophistication, can accurately pinpoint a problem in the CAN bus system. The best even a skilled operator can hope for is to narrow down the field of search somewhat, which means that if the problem persists beyond Step 3, the vehicle should be referred to a specialist for professional diagnosis and repair.

P0601 Erreur de somme de contrôle de la mémoire du module de contrôle interne

• Auteur/autrice de la publication : Eva

Qu’est-ce que ça veut dire?

Ce code de diagnostic (DTC) est un code générique de groupe motopropulseur, ce qui signifie qu’il s’applique aux véhicules équipés d’OBD-II. Bien que génériques, les étapes de réparation spécifiques peuvent varier selon la marque / le modèle.

Fondamentalement, cela signifie qu’il y a un défaut interne dans le module de commande du groupe motopropulseur (PCM). De nombreux échecs PCM ont été signalés sur les produits Chrysler / Dodge, bien qu’il soit possible que cela se produise sur n’importe quel véhicule.

Dans les produits Dodge / Chrysler, un code d’anomalie P0601 signifie qu’une communication série a échoué à l’intérieur de l’ordinateur au moins 6 fois.

Les autres codes d’erreur du module de contrôle interne incluent:

    Erreur de programmation du module de contrôle P0602     P0603 Erreur de maintien de la mémoire vive (KAM) du module de contrôle interne     P0604 Erreur de mémoire vive (RAM) du module de contrôle interne     Erreur de mémoire morte (ROM) du module de contrôle interne P0605

Photo d’un PCM avec le couvercle retiré:

Probablement, aucun symptôme ne sera perceptible pour le conducteur, autre que le témoin Check Engine allumé. En règle générale, le moteur fonctionne bien, les jauges fonctionnent, etc.

Dans la plupart des cas, un code P0601 signifie que le PCM a mal tourné. Cela est peut-être dû à un court-circuit à l’intérieur du PCM. Ou, si vous déconnectez les fils / connecteurs du PCM alors que la batterie est toujours connectée, cela peut également provoquer ce code. Solutions possibles

Avec un code de panne P0601 OBD-II, la solution la plus courante consiste à remplacer et reprogrammer le PCM. Dans certains cas, le revendeur peut reflasher le PCM et le faire fonctionner. Mais il est plus que probable que le PCM devra être remplacé et reprogrammé (nous vous recommandons de le confier à un concessionnaire pour cela). La bonne nouvelle est qu’il * peut * être couvert par votre garantie d’émissions. Donc, même si vous n’avez plus de garantie pare-chocs à pare-chocs ou de groupe motopropulseur, consultez votre guide de garantie ou votre concessionnaire pour voir si cela est couvert.

D’autres personnes ont signalé qu’elles avaient effacé le code uniquement pour qu’il revienne encore et encore. Gardez à l’esprit que la plupart des magasins peuvent remplacer le PCM mais pas tous peuvent le programmer.

Autres codes PCM / ECM: P0600, P0602, P0603, P0604, P0605, P0606, P0607, P0608, P0609, P0610.

I have an 2002 caravan sport with P0601 and P1684. Seems the PCM is the reason but would like to know the basic checks before throwing the cash at it. Seems to me it might be easy enough to plug and unplug the harness. Maybe a bad connection - I will disconnect the battery first. Any suggestions as well as were to find a replacement/reconditioned unit would be appreciated.  

Solo Auto Computers 275. Im getiin ready to order mine....Just tryin to get my money in order. http://www.solopcms.com/  

Everything I've read says the PCM has an internal error and needs to be replaced. No harm in reseating the connector. PCMs have 8 year 80K mile federal emissions warranties on them. You might want to talk to your local dealer to make sure you would qualify. There is one caviot but, don't recall the details. On a side note, I've read around a dozen threads about P0601 codes on various forums and I don't recall anyone having any driveability issues along with the code. The light is on but everything is running just fine. If it weren't for state smog inspections you could just press on, as long as the light doesn't bother you. Then again you could be the first to post your van died in the middle of nowhere with this code.  

check the connection to computer. look for a short or loose wire maybe even a wire that has shortened over time(shrinkage) or for discolor from arking. see if you can reinsert ..if not. splice a length of wire.  

drugdawg said: maybe even a wire that has shortened over time(shrinkage) or for discolor from arking. see if you can reinsert ..if not. splice a length of wire. Click to expand...

Chrysler changed my PCM as well... they had to do it three times... they said that engineering had issues with 06 SEs. Thus they changed the coils and PCM AT THE SAME TIME. Am still figuring it out till now. But one month without trouble is fine with me (except for not so good gas consumption still: 16 liters for every 100 km; city driving!).  

I have a P204 problem with my 01 Caravan. Is it possible that I could get this code and have my PCM fried. So far P601 hasn't shown up. I want to make sure before putting down more money into it. I've swapped my injectors, checked the wirings, swapped plugs and my only conclusion would be the PCM.

I changed mine by purchasing from Solo for $269. The first unit they sent was defective but they gladly turned around another with no problems. I have heard some junkyards wont sell PCMs which may be due to programming odometer and VIN. You can have the PCM reflashed at some dealers for about $89. The one from Solo is already flashed.

Chrysler Town and Country P0601: Meaning, Causes + Diagnosis

P0601 is a somewhat rare OBD2 trouble code.  It’s a generic code (it has the same meaning for the Chrysler Town and Country as it would any other vehicle).

While it indicates that the PCM’s memory failed a memory check, P0601 is commonly seen when people use OBD2 port plugin accessories on their vehicle.  These accessories are used to turn off cylinder deactivation technology, auto engine start/stop, and performance plugins.  If this is the case with your Town and Country, unplugging it may clear the code.

P0601 Definition: Internal Control Module – Memory Checksum Error

Your Chrysler Town and Country’s PCM (powertrain control module) has memory and a processor like any other computer.  The PCM’s processor performs a “checksum test” to verify the integrity of its onboard memory. 

If the PCM fails this self-diagnostic test, P0601 will be stored, and the check engine light will come on.

P0601 Symptoms:  Chrysler Town and Country

The symptoms associated with P0601 are wide-ranging if there are any at all.  It’s likely that your Town and Country will run and drive when normally when this code is present.  Here are the most common symptoms of P0601

• Check engine light – Other codes are likely to be present with P0601.
• No start – The engine will have difficulty starting or won’t start at all.
• Engine performance issues – The PCM controls the engine.  So the engine may stall or act erratically.

Chrysler Town and Country P0601 Causes and Diagnosis

Here are the most common causes of P0601, as well as a proper order of diagnostic operations:

1. Reflashed PCM or OBD2 Dongle

If your computer was reflashed with a tune that Chrysler did not approve, that can cause P0601.  You’ll need to have the PCM reflashed.

Those little dongles that plug into the OBD2 port that modify the way the your Town and Country runs or drives, they are notorious for causing P0601.  If you have one of these, pull it and reset the code.  If it doesn’t come back, you shouldn’t use the dongle anymore.

Most of the time, with P0601, the only solution is to have the PCM replaced or reflashed, which means taking your Town and Country to the dealer.

There’s not a lot you can do to fix P0601 in the Chrysler Town and Country at home.  The good news is that the PCM may be subject to the eight year 80,000 mile federal emissions warranty.  Here’s a link if you want to read more about that.

About the Voyager

The Voyager series of minivans first made their debut in 1988. The first iteration of the model remained on the market until its discontinuation in 2016. Chrysler announced the rebirth of the model under the same nameplate in 2019 and it has remained available until today.

There has also been a rebadged version called the Lancia Voyager sold in the European market.

A total of five generations were released for the first version before its hiatus. The new version represents the sixth generation to hit the markets.

The Voyager sits as the lower-end offering in the Chrysler minivan lineup, putting it below the Dodge Grand Caravan and Chrysler Pacifica . Outside competition includes the Honda Odyssey and Toyota Sienna .

One of the most common issues that owners have had to deal with is fault code P0562 . This code indicates that the battery is showing a low voltage.

Owners have reported that dirty battery terminals are one of the most common causes of the problem, particularly in older models that have gathered some wear and tear. Another likely culprit is a faulty cell in the battery that is not charging properly.

Another fault code that has come up fairly often is P0402 , which indicates that excessive flow has been detected in the EGR system.

Wear and tear can cause the EGR solenoid to fail over time. Voyager models typically need a replacement of this part roughly every 70,000 miles.

Fault code P0406 is another EGR issue that the model has suffered from. This code indicates that there is a high voltage from sensor A.

A sensor issue like this can usually be the result of a failing sensor or electrical issues within the sensor circuit.

Here at FaultCodes.co you can find the meanings behind OBD2 codes.

OBD2 codes are the readings presented by an automobile when it has detected an error within itself.

Typically you will see an engine warning light on your dashboard to inform you that something is wrong, if you plug in an OBD2 reader you can find out the exact cause of that problem.

By entering the OBD2 fault code on this website you can find out where the issue is in text form.
