DIAGNOSTIC TROUBLE CODE (DTC) CHART
Inspection and Verification
- Verify the customer concern.
- Visually inspect the following for obvious signs of electrical damage. VISUAL INSPECTION CHART Electrical Battery junction box (BJB) fuses: 1 (50A) 2 (50A) 3 (50A) Smart junction box (SJB) fuse 2 (5A) Circuitry SJB
- 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 «MODULE COMMUNICATIONS NETWORK»(ref-270934) , No Power To The Scan Tool, to diagnose no communication with 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 «MODULE COMMUNICATIONS NETWORK»(ref-270934) to diagnose no response from the powertrain control module (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-270934) . 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 «Diagnostic Trouble Code (DTC) Chart»(ref-270935-S38943114312007110700000) .
- If no DTCs related to the concern are retrieved, go to «Symptom Chart»(ref-270935-S34606162452007111500000) .
