Is the Smart key unit in the 'Learnt' state?
YES
- Fault can be intermittent, caused by poor contact of connectors between the IBU (SMK+BCM+TPMS) and the ECM. Or, ECM memory was not cleared after repair. Thoroughly check connectors for looseness, poor contact, bending, corrosion, contamination, deterioration, or damage. Repair or replace relevant component(s) as necessary and then go to "VERIFICATION OF VEHICLE REPAIR ".
NO
- Go to next procedure.
