Component Testing

Relay Test

1. Ignition OFF, disconnect the KR5 Rear Defogger Relay.
2. Test for 60-180Ω between terminals 85 and 86.
   • If less than 60Ω or greater than 180Ω 

     Replace the KR5 Rear Defogger Relay.

   • If between 60-180Ω 
3. Test for infinite resistance between the terminals listed below:
   • 30 and 86
   • 30 and 87
   • 30 and 85
   • 85 and 87
   • If less than infinite resistance 

     Replace the KR5 Rear Defogger Relay.

   • If infinite resistance 
4. Install a 3A fused jumper wire between relay terminal 85 and 12V. Install a jumper wire between relay terminal 86 and ground.
5. Test for less than 2Ω between terminals 30 and 87.
   • If 2Ω or greater 

     Replace the KR5 Rear Defogger Relay.

   • If less than 2Ω 
6. All OK
