Diagnostic Test

WARNING: This page is about a different car, the 2014 Dodge Journey. However, it is still accessible from the selected car via links, so may be relevant.

CHECK THE POWER AND GROUND CIRCUITS 

  1. This DTC is set when the PCM is initialized while the vehicle is moving in a valid forward gear. This is usually caused by a momentary loss of power to the Transmission portion of the PCM.
  2. Check all of the Fused B(+), Fused Ignition Switch Output, and Ground circuits related to the PCM for an intermittent open or short to ground.
  3. Perform a wiggle test on all wiring and connectors pertaining to the PCM while looking for shorted or open circuits.
  4. With the scan tool, check the Event Data to help identify the conditions in which the DTC was set.
