Component Testing

Relay Test

1. Ignition OFF, disconnect the RR DEFOG relay.
2. Test for 60 - 180 ohms between terminals 85 and 86.
   • If not within the specified range, replace the relay.
3. Test for infinite resistance between the following terminals:
   • 30 and 86
   • 30 and 87
   • 30 and 85
   • 85 and 87
   • If not the specified value, replace the relay.
4. Install a 25-amp fused jumper wire between relay terminal 85 and 12 volts. Install a jumper wire between relay terminal 86 and ground. Test for less than 2 ohms between terminals 30 and 87.
   • If greater than the specified range, replace the relay.
