2002 Dodge Durango 4.7L 56029202AA – PCM ECM ECU Control Module (Engine Computer) Replacement

The Powertrain Control Module, or PCM, is a pre-programmed digital computer that operates the engine control system of a vehicle. It is sometimes referred to as JTEC. As the input data changes, the PCM adjusts its response to the various output devices it operates.  If the PCM, the “brains”, fails to work correctly, the rest of the engine will have issues as well. Luckily, if proper diagnosis points toward replacement of the PCM as the solution, the PCM can be easily replaced to fix the issue. We’ll show you how to replace a PCM ECM ECU Module on a 2002 Dodge Durango.

LOCATION

Begin replacing the PCM of your 2002 Dodge Durango by locating the module. The location of the PCM is in the engine compartment in the back right near the battery. Before we start, make sure to do this to ensure safe replacement. Turn off the ignition key and disconnect the negative battery cable before unplugging the PCM connectors. This will protect the PCM from possible voltage spike damage.

REMOVAL

1- Disconnect and isolate the negative battery cable from the battery.

2- Remove the cover over the electrical connectors.

3- Carefully unplug the 32–way connectors from the PCM.
