Circuit/System Verification
Install a 12 V DC accessory into a X80 accessory power receptacle or activate the E32 cigarette lighter. Vehicle in Service Mode, command the Auxiliary Power Relay Command ON and OFF with a scan tool. The K10 RAP relay should click and the 12 V DC accessory or the E32 cigarette lighter should have power.
Circuit/System Testing
Accessory Power Receptacle or Cigarette Lighter Malfunction
1. Vehicle OFF, disconnect the K10 RAP 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. Vehicle in Service Mode, 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.
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.
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.
9. Connect a 20 A fused jumper wire between the K10 RAP relay B+ circuit terminal 87 and the control circuit terminal 30. Verify the accessory has power.
• If the accessory 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 appropriate X80 accessory power receptacle or E32 cigarette lighter.
10. If all circuits test normal, test or replace the K10 RAP relay.
Component Testing
Relay Test
1. Vehicle OFF, disconnect the K10 RAP 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.
