Circuit/System Verification

Install a 12 V DC accessory into a X80 accessory power receptacle or activate the cigarette lighter. Ignition ON, command the Auxiliary Power Relay Command ON and OFF with a scan tool. The KR70 auxiliary power 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. 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.

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 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.
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 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 KR70 auxiliary power.

Cigarette Lighter LED Malfunction

1. Disconnect the harness connector at the E32 cigarette lighter.
2. 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.

3. Ignition ON, interior lights dimmer switch on high, verify that a test lamp illuminates between the control circuit terminal B and ground.

⇒	If the test lamp does not illuminate, test the control circuit for a short to ground or an open/high resistance.

4. If all circuits test normal, replace the E32 cigarette lighter.

Component Testing

Relay Test

1. Ignition OFF, disconnect the KR70 auxiliary power.
2. Test for 60-180 Ω 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 Ω between terminals 30 and 87.

⇒	If greater than specified range, replace the relay.
