Control Relay Power Circuit Inspection
- Check short to ground in harness
- IG "OFF". Disconnect EMS box and PCM connector.
- Measure the resistance between control relay power terminal of main relay (EMS box) harness connector and chases ground.
Specification : Infinite
- Is the measured resistance within specification?
YES
- Go to " 2 Check open in harness" procedure.
NO
- Repair short to ground in control harness. Go to "VERIFICATION OF VEHICLE REPAIR " procedure.
- Check open in harness
- IG "OFF". Disconnect EMS box and PCM connector.
