Inspection and Verification
- Verify the customer concern.
- Visually inspect for obvious signs of electrical damage. VISUAL INSPECTION CHART Electrical Battery junction box (BJB) fuse 39 (100A) Smart junction box (SJB) fuse(s): 5 (10A) SJB 6 (20A) exterior lighting (stop/turn lamps) 7 (10A) exterior lighting (headlamps) 8 (10A) exterior lighting (headlamps) 9 (15A) interior lighting 10 (15A) interior lighting 17 (20A) door locks/ajar switches 21 (15A) exterior lighting (cornering/fog lamps)
- 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-357141) article, 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-357141) article 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-357141) article. 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 «DTC Charts»(ref-357142-S34388149882010030800000) .
- If no DTCs related to the concern are retrieved, go to «Symptom Chart»(ref-357142-S30790893372010030800000) .

SYMPTOM CHART
PINPOINT TEST A: DTC B106E - SOLID STATE DRIVER DISABLED DUE TO SHORT CIRCUIT
Note. If DTC B106F is present and a new SJB is to be installed, the fault condition must be corrected first. Failure to correct the fault condition first may cause damage to the new SJB, resulting in a repeat repair.
- A1 REVIEW THE DTCs Review the DTCs from the SJB self-test. Are only DTCs B106E and B106F present? YES : INSTALL a new SJB. REFER to «Smart Junction Box (SJB)»(ref-357142-S15369768372010030800000) . TEST the system for normal operation. NO : CORRECT any DTCs present other than DTCs B106E and B106F. REFER to «DTC Charts»(ref-357142-S34388149882010030800000) . After the repair, go to A2 .
- A2 CARRY OUT THE SJB SELF-TEST Carry out the SJB self-test. Is DTC B106F present? YES : INSTALL a new SJB. REFER to «Smart Junction Box (SJB)»(ref-357142-S15369768372010030800000) . TEST the system for normal operation. NO : The system is operating correctly at this time. The concern was caused by a fault in one of the output circuits.
PINPOINT TEST B: DTCs B2048, B2050, B2949, B2A2B, B2A2C, B2A38 - POSSIBLE SMART JUNCTION BOX (SJB) INTERNAL ERRORS
- B1 CHECK FOR CORRECT SJB OPERATION Disconnect all the SJB connectors. Check for: corrosion damaged pins pushed-out pins Connect all the SJB connectors and make sure they seat correctly. Enter the following diagnostic mode on the diagnostic tool: Clear the SJB DTCs Enter the following diagnostic mode on the diagnostic tool: Repeat the SJB Self-Test Is DTC B2048, B2050, B2949, B2A2B, B2A2C, or B2A38 retrieved (or any combination of the previously mentioned DTCs)? YES : INSTALL a new SJB. REFER to «Smart Junction Box (SJB)»(ref-357142-S15369768372010030800000) . CLEAR the DTCs. REPEAT the self-test. TEST the system for normal operation. NO : The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector. CLEAR the DTCs. REPEAT the self-test. TEST the system for normal operation.
