The P068B fault code refers to a problem with the Engine Control Module (ECM) in your vehicle.

The ECM is responsible for monitoring the power inputs in your car. When the ignition switch is turned off, the ECM should also power down.

However, if the ECM remains powered up after the ignition switch has been turned off, the P068B code is set. This code indicates that there is an issue with the performance of the ECMPCM power relay being de-energized too slowly.

It is important to address this issue promptly to ensure proper functioning of your vehicle’s ECM.
