Diagnostic Test

CHECK THE POWER AND GROUND CIRCUITS
1. This DTC is set when the Transmission portion of the Powertrain Control Module is initialized while the vehicle is moving down the road in a valid forward gear.
2. Using the SYSTEM WIRING DIAGRAMS as a guide, inspect the wiring and connectors.
3. Check all of the Fused B(+), Fused Ignition Switch Output, and ground circuits to the PCM for an intermittent open or short to ground.
4. With the scan tool, check the Event Data to help identify the conditions in which the DTC was set.
  Repair
  - Check all power and ground circuits to the PCM and repair as necessary.
  - Perform the 545RFE TRANSMISSION VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure .
