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. Thoroughly check terminal of 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
- Carefully re-do this troubleshooting guide steps.
- Repair open or short in circuit and then go to "VERIFICATION OF REPAIR " procedure.
- If problem still occurs, replace control unit that causing the fault and then go to "VERIFICATION OF REPAIR " procedure.
