What is a PCM on a Dodge Charger?

A Charger powertrain module, or PCM, is a consolidated module boasting an ECM linked to a transmission control unit, or TCM. All of these components are electronic control units, or ECUs, controlling electrical systems and subsystems throughout your Charger.

How can you tell if a PCM is bad?

What Are the Symptoms of a Faulty PCM?

1. Your “check engine” light is on.
2. Other warning lights may be on, including traction control and ABS.
3. You lose fuel economy for no apparent reason.
4. Your car stutters when starting, requires multiple attempts, or won’t start at all.
5. Stuttering or stalling during idling.

How much does a new PCM cost?

In some cars, there are multiple computers, and with other cars, there are just a few. The PCM controls more than 100 factors in your car, and for that reason, is very important – and expensive. A typical pcm replacement cost comes to between $500 and $1,500 on average.

Can a bad PCM drain your battery?

Battery drain or dead battery A failed ECM power relay can also cause a battery drain or dead battery. If the relay shorts it can leave power on to the computer, even when the vehicle is turned off. This will place a parasitic drain on the battery, which will eventually cause it to go dead.

How much does ECM cost?

The cost for the new ECM will typically be around $800, with labor around $100, bringing the average total expense for an ECM replacement to approximately $900 before taxes and fees. This can increase depending on the shop you go to or the type of car you, running as high as $2,000.

What causes an ECM to go bad?

Corrosion and moisture Corrosion or damage due to moisture is one of the main reasons for ECM failure. Corrosion can enter the ECM through the wiring harness and moisture can enter by a failure in the seals in the ECM itself. This happens over a period of time (5 to 10 years) due to the ECMs exposure to the elements.
