Circuit/System Verification
|
Install a 12 V DC accessory into a X80 accessory power receptacle. Ignition ON, command the Accessory/Retained Accessory Power Relay Command ON and OFF with a scan tool. The KR76 relay for retained accessory current should click and the 12 V DC accessory should have power.
Accessory Power Receptacle Center Console or Instrument Panel
|
1.
|
Switch off the ignition and disconnect the KR76 relay for the retained accessory current.
|
|
2.
|
Test for less than 10 Ω between the ground circuit terminal 86 and ground.
|
|
3.
|
If greater than the specified range, test the ground circuit for an open/high resistance.
|
|
4.
|
Verify that a test lamp does not illuminate between the control circuit terminal 30 and ground.
|
|
5.
|
If the test lamp illuminates, test the control circuit for a short to voltage.
|
|
6.
|
Ignition ON, verify that a test lamp illuminates between the control circuit terminal 85 and ground.
|
|
7.
|
If the test lamp is always OFF, test the control circuit for a short to ground or an open/high resistance. If all circuits test normal, replace the K9 BCM.
|
|
8.
|
Verify that a test lamp illuminates between the B+ circuit terminal 87 and ground.
|
|
9.
|
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.
|
|
10.
|
Ignition OFF, disconnect the harness connector at an inoperative X80 accessory power receptacle.
|
|
11.
|
Test for less than 10 Ω between the X80 accessory power receptacle ground circuit terminal C and ground.
|
|
12.
|
If greater than the specified range, test the ground circuit for an open/high resistance.
|
|
13.
|
Connect the harness connector at the X80 accessory power receptacle.
|
|
14.
|
Connect a 20 A fused jumper wire between the K76 relay for retained accessory current B+ circuit terminal 87 and the control circuit terminal 30. Verify the 12 V DC accessory receptacle has power.
|
|
15.
|
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.
|
|
16.
|
If all circuits give normal test values test or replace KR76 relay for retained accessory current.
|
Accessory Power Receptacle Rear Compartment
|
1.
|
Disconnect the harness at the X80R accessory power receptacle-rear compartment.
|
|
2.
|
Test for less than 10 Ω between the ground circuit terminal C and ground.
|
|
3.
|
If greater than the specified range, test the ground circuit for an open/high resistance.
|
|
4.
|
Verify that a test lamp illuminates between the B+ circuit terminal A and ground.
|
|
5.
|
If the test lamp does not illuminate, test the B+ circuit for an open/high resistance or a short to ground.
|
|
6.
|
If all circuits test normal, replace the X80R accessory power receptacle - luggage compartment.
|
Relay Test
|
1.
|
Switch off the ignition and disconnect the KR76 relay for the retained accessory current.
|
|
2.
|
Test for 60-180 Ω between terminals 85 and 86.
|
|
3.
|
If not within the specified range, replace the relay.
|
|
4.
|
Test for infinite resistance between the following terminals:
|
|
5.
|
If not the specified value, replace the relay.
|
|
6.
|
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.
|
|
7.
|
If greater than specified range, replace the relay.
|
Perform the
Diagnostic Repair Verification
after completing the diagnostic procedure.
