KEYLESS CONTROL MODULE INSPECTION [WITH KEYLESS ENTRY SYSTEM]
- Measure the voltage or inspect for continuity according to the «TERMINAL VOLTAGE TABLE»(ref-244528-S19504569912006092400000) . If the voltage is not as specified in the «TERMINAL VOLTAGE TABLE»(ref-244528-S19504569912006092400000) , inspect the parts under "Inspection item(s)" and related wiring harnesses.
