Troubleshooting
•
If shorted to positive: check the relay electrical specifications are correct by disconnecting
it from the cable harness. If they are not correct, replace the relay; if OK, restore the cable
harness (blue/pink cable)
•
If shorted to negative: check the relay electrical specifications are correct by disconnecting

harness (blue/pink cable)
•
If the circuit is open: check the relay electrical characteristics are correct by disconnecting
it from the cable harness; if not OK, replace the relay, if OK, check relay connector, engine-
