Inspection and Verification
- Verify the customer concern.
- Visually inspect for obvious signs of electrical damage. VISUAL INSPECTION CHART Electrical Smart Junction Box (SJB) fuse 5 (10A) Wiring, terminals or connectors SJB
- If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step.
- 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).
- 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 VCM Check the VCM connection to the vehicle. Check the scan tool connection to the VCM. Refer to «MODULE COMMUNICATIONS NETWORK»(ref-574111) , 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 is in the ON state. Verify the scan tool operation with a known good vehicle. Refer to «MODULE COMMUNICATIONS NETWORK»(ref-574111) to diagnose no response from the PCM.
- Carry out the network test. If the scan tool responds with no communication for one or more modules, refer to «MODULE COMMUNICATIONS NETWORK»(ref-574111) . 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 SJB.
- If the DTCs retrieved are related to the concern, go to the «Smart Junction Box (SJB) DTC Chart»(ref-574135-S33486518212013082300000) .
- If no DTCs related to the concern are retrieved, GO to «SYMPTOM CHART»(ref-574135-S37638034022013082300000) .
