■ Check short in harness 

1. IG "OFF". Disconnect the main relay and PCM connector.
2. Measure the resistance between control terminal of main relay harness connector and chassis ground.

   Specification:  Infinite

3. Is the measured resistance within specification?

   YES 

   • Go to "Check open in harness" procedure below.

   NO 

   • Repair short in control harness. Go to "VERIFICATION OF VEHICLE REPAIR " procedure.
