PCM Repair FAQs

The powertrain control module (PCM), or the engine control module (ECM), is the “brain” of your car. It is connected to a variety of engine components, and is able to alert the driver if something is not functioning correctly.

Below are the answers to some of the most frequently asked questions that the team at My Auto Solutions in Duluth, GA, receives about PCM repair.

What Does the Powertrain Control Module Do?

The PCM regulates the majority of functions for your car. Working as a “brain” for your car’s engine control, if the PCM is not working properly, your car’s engine, transmission, or charging system may suffer. Your PCM senses many components of your engine and will alert you (usually with the check engine light) if something in not functioning correctly.

What Are the Signs of PCM Failure?

Although the signs of PCM or ECM failure can vary, the most common indicators include:

  • Check engine light on
  • Power loss
  • Slow start, or no start
  • Poor fuel economy
  • Rattling engine noise when car is parked or neutral
  • Engine stalls

If you notice any of these signs of PCM failure, it is important to seek repair as soon as possible.

How Do I Repair my PCM?

The good thing about PCM repair is that you do not always have to replace the unit. In many cases, our technicians run several diagnostic tests which can pinpoint the problem, and then repair it.

When diagnosing issues with your PCM, technicians can determine was the issues are by use of diagnostic trouble codes. The PCM can communicate by use of OBD codes, where the car’s onboard control modules may be misfiring.

Which OBD Codes Indicate PCM Failure?

Onboard diagnostic (OBD) codes that most often point to a problem with the powertrain control module include:

  • P0600: Serial Communication Link
  • P0601: Internal Control Module Memory Check Error
  • P0602: Control Module Programming Error
  • P0603: Internal Control Module KAM Error
  • P0603: Internal Control Module RAM Error
  • P0605: Internal Control Module ROM Error
  • P0606: ECM/PCM Processor
