Using the wiring diagrams as a guide, check all related splices and connectors for signs of water intrusion, corrosion, pushed out or bent terminals and correct pin tension. If no problems are found, test complete.
  - Perform the BODY VERIFICATION TEST. Refer to BODY VERIFICATION TEST .
CHECK THE (F20) IGNITION RUN - START OUTPUT CIRCUIT AT THE BCM
1. Turn the ignition off.
2. Disconnect the BCM C5/E harness connector.
3. Turn the ignition on.
4. Measure the voltage between ground and the (F20) Ignition Run - Start Output circuit at the BCM C5/E harness connector.
  Is the voltage above 10.0 volts?
  
  Yes
  - Go To 5
  No
  - Go To 3
CHECK THE (F20) IGNITION RUN - START OUTPUT CIRCUIT FOR A SHORT TO GROUND
1. Turn the ignition off.
2. Disconnect the Radio Frequency (RF) Hub Module C1 harness connector.
3. Check for continuity between ground and the (F20) Ignition Run - Start Output circuit at the RF Hub Module C1 harness connector.
  Is there continuity between ground and the (F20) Ignition Run - Start Output circuit?
  
  Yes
  - Repair the short to ground on the (F20) Ignition Run - Start Output circuit.
  - Perform the BODY VERIFICATION TEST. Refer to BODY VERIFICATION TEST .
  No
  - Go To 4
CHECK THE (F20) IGNITION RUN - START OUTPUT CIRCUIT FOR AN OPEN
1. Measure the resistance of the (F20) Ignition Run - Start Output circuit between the RF Hub Module C1 harness connector and the BCM C5/E harness connector.
  Is the resistance above 3.0 Ohms?
  
  Yes
  - Repair the open in the (F20) Ignition Run - Start Output circuit.
  - Perform the BODY VERIFICATION TEST. Refer to BODY VERIFICATION TEST .
  No
  - Go To 6
CHECK THE BCM
1. Turn the ignition off.
2. Inspect the wiring and connectors of the BCM for pushed out, bent or broken terminals.
3. Verify that there is good pin to terminal contact.
4. Connect the BCM C5/E harness connector.
5. With the scan tool, read the BCM DTCs.
  Is the DTC active?
  
  Yes
  - Replace the Body Control Module (BCM) in accordance with the Service Information. Refer to MODULE, BODY CONTROL, REMOVAL .
  - Perform the BODY VERIFICATION TEST. Refer to BODY VERIFICATION TEST .

CHECK THE RF HUB MODULE
1. Turn the ignition off.
2. Inspect the wiring and connectors of the RF Hub Module for pushed out, bent or broken terminals.
3. Verify that there is good pin to terminal contact.
4. Connect the RF Hub Module C1 harness connector.
5. With the scan tool, read the BCM DTCs.
  Is the DTC active?
  
  Yes
  - Replace the RF Hub Module in accordance with the Service Information. Refer to MODULE, RADIO FREQUENCY (RF HUB), REMOVAL .
  - Perform the RADIO FREQUENCY HUB (RF HUB) VERIFICATION TEST. Refer to RADIO FREQUENCY HUB (RF HUB) VERIFICATION TEST .
  No
  - Test complete.
  - Perform the BODY VERIFICATION TEST. Refer to BODY VERIFICATION TEST .
