Diagnostic Test
- CHECK THE POWER AND GROUND CIRCUITS
- 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.
- 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.
- Perform a wiggle test on all wiring and connectors pertaining to the PCM while looking for shorted or open circuits.
- With the scan tool, check the DTC EVENT DATA to help identify the conditions in which the DTC was set.
