A1 REVIEW THE DTCs
NOTE: First follow the necessary diagnostics to resolve DTC B106E and any other present DTCs (ignoring B106F). DTC B106E is only present when there is another DTC due to software or circuitry issues that must be resolved before another self-test is run. DTC B106F is only present once the final threshold has been met. Failure to correct the fault condition first may cause damage to the new SJB, resulting in a repeat repair.
- Review the DTCs from the SJB self-test.
- Are any other DTCs present, besides B106E, B106F or B1342?
- Yes : CORRECT the DTCs. REFER to the Smart Junction Box (SJB) DTC chart . After the repair, GO to A2.
- No : GO to A2.
A2 REPEAT THE SJB SELF-TEST
- Ignition ON.
- Enter the following diagnostic mode on the scan tool: SJB Self-Test.
- Clear the DTCs and repeat the SJB self-test.
- Is DTC B106F or DTC B1342 present?
- Yes : INSTALL a new SJB. REFER to SMART JUNCTION BOX (SJB) . TEST the system for normal operation.
- No : The system is operating correctly at this time. The circuit short has been repaired.
