Circuit/System Testing

  1. Ignition OFF, disconnect the KR70 auxiliary power relay.
  2. Test for less than 10 Ω between the ground circuit terminal 86 and ground.
    • If greater than the specified range, test the ground circuit for an open/high resistance.
  3. Verify that a test lamp does not illuminate between the control circuit terminal 30 and ground.
    • If the test lamp illuminates, test the control circuit for a short to voltage.
  4. Ignition ON, verify that a test lamp illuminates between the ignition circuit terminal 85 and ground.
    • If the test lamp does not illuminate, test the ignition circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the K9 BCM.
  5. Verify that a test lamp illuminates between the B+ circuit terminal 87 and ground.
    • If the test lamp does not illuminate, test the B+ circuit for a short to ground or an open/high resistance. If the circuit tests normal and the B+ circuit fuse is open, test the control circuit terminal 30 for a short to ground.
  6. Disconnect the harness connector at the inoperative X80 accessory power receptacle or E32 cigarette lighter receptacle.
  7. Test for less than 10 Ω between the ground circuit terminal C and ground.
    • If greater than the specified range, test the ground circuit for an open/high resistance.
  8. Connect the harness connector at the X80 accessory power receptacle or E32 cigarette lighter receptacle.
  9. Connect a 20 A fused jumper wire between the KR70 auxiliary power relay B+ circuit terminal 87 and the control circuit terminal 30. Verify the 12 V DC accessory has power.
    • If the 12 V DC does not have power, test the control circuit for a short to ground or an open/high resistance. If the circuit tests normal, test or replace the X80 accessory power receptacle or E32 cigarette lighter receptacle.
  10. If all circuits test normal, test or replace the KR70 auxiliary power relay.
