Circuit/System Verification
Install a 12 V DC accessory into the X80 accessory power receptacle. Ignition ON, command the Accessory/Retained Accessory Power Relay Command ON and OFF with a scan tool. The K10 RAP relay should click and the 12 V DC accessory should have power.
Circuit/System Testing
1. Ignition OFF, disconnect the KR70 auxiliary power relay.
2. Test for less than 10 ohm 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 ohm 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.
Component Testing
Relay Test
1. Ignition OFF, disconnect the KR70 auxiliary power relay.
2. Test for 60-180 ohm 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 20 A fused jumper wire between relay terminal 85 and 12 V. Install a jumper wire between relay terminal 86 and ground. Test for less than 2 ohm between terminals 30 and 87.
• If greater than specified range, replace the relay.
