3. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step.

4. NOTE: Make sure to use the latest scan tool software release.

If the cause is not visually evident, connect the scan tool to the Data Link Connector (DLC).

5. NOTE: The Vehicle Communication Module (VCM) LED prove-out confirms power and ground from the DLC are provided to the VCM.

If the scan tool does not communicate with the vehicle:
- Verify the ignition is ON.

- The air bag warning indicator prove-out confirms ignition ON (other indicators may NOT prove ignition is ON) confirms ignition ON. If ignition does not turn ON, refer to Steering Column to diagnose no power in RUN.

- Verify the scan tool operation with a known good vehicle.

- Refer to Information Bus, Inspection and Verification to establish a scan tool session.

6. NOTE: The ignition must be OFF to carry out the Remote Function Actuator (RFA) module self-test.

Carry out the self-test diagnostics for the RFA module and Parking Aid Module (PAM).
