Good
- Fault is intermittent caused by poor contact in TPMS's connector or was repaired and IBU memory was not cleared.
- Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage.
- Repair or replace as necessary, go to "VERIFICATION OF REPAIR " procedure.
No Good
- Carefully re-do this troubleshooting guide steps.
- Repair as necessary and then go to "VERIFICATION OF REPAIR " procedure.
- If no problems were found with the circuits or connectors, replace HECU and then go to "VERIFICATION OF REPAIR " procedure.
