- Verify the customer concern.
- Visually inspect for obvious signs of electrical damage.VISUAL INSPECTION CHART
Electrical - Smart Junction Box (SJB) fuse 35 (10A)
- Parking aid sensors
- Reversing lamps
- Wiring, terminals or connectors
- If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step.
- If the cause is not visually evident, connect the scan tool to the Data Link Connector (DLC).
- If the scan tool does not communicate with the VCM:
- Check the VCM connection to the vehicle.
- Check the scan tool connection to the VCM .
- Refer to PINPOINT TEST W: NO POWER TO THE SCAN TOOL , No Power To The Scan Tool, to diagnose no power to the scan tool.
- If the scan tool does not communicate with the vehicle:
- Verify the ignition key is in the ON position.
- Verify the scan tool operation with a known good vehicle.
- Refer to PINPOINT TEST A: THE PCM DOES NOT RESPOND TO THE SCAN TOOL , The PCM Does Not Respond To The Scan Tool.
- Carry out the network test.
- If the scan tool responds with no communication for one or more modules, refer to PINPOINT TEST J: THE PARKING AID MODULE (PAM) DOES NOT RESPOND TO THE SCAN TOOL to diagnose The Parking Aid Module (PAM) Does Not Respond To The Scan Tool.
- If the network test passes, retrieve and record the continuous memory DTCs.
- Clear the continuous DTCs and carry out the self-test diagnostics for the PAM .
- If the DTCs retrieved are related to the concern, go to DTC CHARTS . For all other DTCs, refer to the Diagnostic Trouble Code (DTC) Chart in DIAGNOSTIC TROUBLE CODE (DTC) CHART .
