Good
- Fault might be intermittent and caused either by poor contact in connectors or wiring harness, or it has been repaired and control module memory is not cleared yet. Therefore check terminal of auxiliary battery, all connectors and connections for looseness, bending, corrosion, contamination, deterioration, and/or damage.
- Repair or replace as necessary and then go to "Verification of Repair " procedure.
No Good
- Check the fuse condition.
- Repair as necessary and then go to "Verification of Repair " procedure.
- If no problems were found with the circuits or connectors, replace the PCB block and go to "Verification of Repair " procedure.
