Diagnostic Test

CHECK FOR ACTIVE DTC
1. With the scan tool, read the active DTC's.
2. Cycle the ignition switch from off to on, leaving the ignition on for a minimum of 90 seconds.
3. With the scan tool, read the active DTC's.
  Does the scan tool display this DTC as active?
  
  Yes
  - Go to Step 2.
  No
  - If the DTC is stored, check for an intermittent condition. Visually inspect the related wiring harness connectors. Look for broken, bent, pushed out, or corroded terminals.
ACCESSORY DELAY RELAY
1. Turn the ignition off.
2. Install a substitute relay in place of the original Accessory Delay Relay.
3. Cycle the ignition switch from off to on, leaving the ignition on for a minimum of 90 seconds.
4. With the scan tool, read the DTC's.
  Does the scan tool display this DTC as active?
  
  Yes
  - Go to Step 3.
  No
  - Replace the original Accessory Delay Relay.
  - Perform BODY VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Totally Integrated Power (TIPM) - Standard Procedure .

1. Turn the ignition off.
2. Remove the Accessory Delay Relay from the Rear Power Distribution Module.
3. Measure the resistance of the (P307) Accessory Delay Relay Control circuit from the TIPM C3 connector to the Relay connector.
  Is the resistance below 10K ohms?
  
  Yes
  - Go to Step 4.
  No
  - Repair the (P307) Accessory Delay Relay Control circuit for an open.
  - Perform BODY VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Totally Integrated Power (TIPM) - Standard Procedure .

1. Measure the resistance between ground and the (P307) Accessory Delay Relay Control circuit at the relay cavity (85).
  Is the resistance below 100.0 ohms?
  
  Yes
  - Repair the (P307) Accessory Delay Relay Control circuit for a short to ground.
  - 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 the TIPM in accordance with the service information.
