1. Turn the ignition off.
2. Remove the Accessory Delay Relay from the Rear Power Distribution Module.
3. Measure the voltage of the (P307) Accessory Delay Relay Control circuit at the relay connector (cavity 85).
  Is there any voltage present?
  
  Yes
  - Repair the (P307) Accessory Delay Relay Control circuit for a short to voltage.
  - Perform BODY VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Totally Integrated Power (TIPM) - Standard Procedure .
  No
  - Inspect the wiring and connectors for damage or shorted circuits. If OK, replace and program the TIPM in accordance with the service information.
