Good
- If wiring and connectors are intact and symptoms persist, Check the brake system and replace the IEB module if necessary and then Go to "Verification Of Repair " procedure.
No 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 auxiliary battery, all connectors (and connections) for looseness, bending, corrosion, contamination, deterioration, or damage.
- Check and repair CAN lines for open circuits or short circuits, Go to "Verification Of Repair " procedure.
