Component Testing

Relay Test

1. Ignition OFF, disconnect the KR98 Vehicle Level Control Compressor Relay.
2. Test for 60 - 180 Ω between terminals 85 and 86.
   • If less than 60 or greater than 180 Ω 

     Replace the KR98 Vehicle Level Control Compressor Relay.

   • If between 60 - 180 Ω 
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 KR98 Vehicle Level Control Compressor Relay.

   • If infinite resistance 
4. Install a 20 A fused jumper wire between relay terminal 85 and 12 V. Install a jumper wire between relay terminal 86 and ground.
5. Test for less than 2 Ω between terminals 30 and 87A.
   • If 2 Ω or greater 

     Replace the KR98 Vehicle Level Control Compressor Relay.

   • If less than 2 Ω 
6. All OK
