Visual/Physical Inspection
- Inspect for aftermarket devices which can affect the operation of the power outlets. Refer to «Checking Aftermarket Accessories»(ref-364488-S07680217832010063000000)
- Inspect the accessible system components or the visible system components for obvious damage or for obvious conditions which can cause the symptom.
Symptom List
Refer to Power Outlet Receptacle Malfunction (12V DC) or Power Outlet Receptacle Malfunction (110V AC) in order to diagnose the system.
Diagnostic Instructions
- Perform the «Diagnostic System Check - Vehicle»(ref-364486-S08087544882010063000000) prior to using this diagnostic procedure.
- Review «Strategy Based Diagnosis»(ref-364486-S25727745392010063000000) for an overview of the diagnostic approach.
- «Diagnostic Procedure Instructions»(ref-364486-S17107648382010063000000) provides an overview of each diagnostic category.

Circuit/System Testing
- Ignition OFF, disconnect the harness connector at the appropriate X80 accessory power receptacle.
- Test for less than 5 ohms between the ground circuit terminal C and ground. If greater than the specified range, test the ground circuit for an open/high resistance.
- Ignition ON, verify that a test lamp illuminate between the B+ circuit terminal A and ground. If the test lamp does not illuminate, test the B+ circuit for a short to ground or an open/high resistance.
- If all circuits test normal, test or replace the X80 accessory power receptacle.
- Perform the «Diagnostic System Check - Vehicle»(ref-364486-S08087544882010063000000) prior to using this diagnostic procedure.

- Ignition OFF, disconnect the harness connectors at the T1 Accessory DC/AC power inverter module.
- Test for less than 10 ohms between the ground circuit terminal 1 X2 and ground. If greater than the specified range, test the ground circuit for an open/high resistance.
- Verify that a test lamp illuminates between the B+ circuit terminal 2 X2 and ground. If the test lamp does not illuminate, test the B+ circuit for a short to ground or an open/high resistance.
- Ignition ON, test for less than 1.0 V between the AC circuit terminals listed below and ground: Terminal 4 X1 Terminal 6 X1 If greater than the specified range, test the AC circuit for a short to voltage.
- Ignition OFF, test for infinite resistance between the AC circuit terminals listed below and ground: Terminal 4 X1 Terminal 6 X1 If less than the specified value, test the AC circuit for a short to ground.
- Disconnect the harness connector at the X81 accessory power receptacle - 110 V AC.
- Ignition ON, verify a test lamp illuminates between the control circuit terminal 4 and ground. If the test lamp does not illuminate, test the control circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the K9 BCM.
- Verify a test lamp does not illuminate between the signal terminal 1 and ground. If the test lamp illuminates, test the signal circuit for a short to voltage. If the circuit tests normal, replace the T1 Accessory DC/AC power inverter module.
- Connect a 3 A fused jumper between the control terminal 4 and the signal terminal 1.
- Ignition ON, verify that a test lamp illuminates between the T1 Accessory DC/AC power inverter module signal circuit terminal 2 X1 and ground. If the test lamp does not illuminate, test the signal circuit for a short to ground or an open/high resistance.
- Ignition OFF, connect the harness connectors at the T1 Accessory DC/AC power inverter module. Ignition ON, test for 110-120 V AC between the X81 accessory power receptacle - 110 V AC terminal 3 and 6. If not within the specified range, check both AC circuits for an open/high resistance. If all circuits test normal, replace the T1 Accessory DC/AC power inverter module.
- If all circuits test normal, replace the X81 accessory power receptacle - 110 V AC.
Component Testing
Accessory Power Outlet
- Ignition OFF, remove the X80 accessory power receptacle - 110 V AC.
- Test for greater than 1 M ohms between terminal 3 and terminal 6. If less than the specified range, replace the X80 accessory power receptacle - 110 V AC.
- Test for less than 3 ohms between the following terminals: The terminal 3 and the applicable receptacle terminal The terminal 6 and the applicable receptacle terminal If greater than the specified range, replace the X80 accessory power receptacle - 110 V AC.
- Test for infinite resistance between terminal 4 and terminal 1. If not the specified value, replace the X80 accessory power receptacle - 110 V AC.
- Connect an AC powered device to the X80 accessory power receptacle - 110 V AC.
- Test for less than 3 ohms between terminal 4 and terminal 1. If greater than the specified range, replace the X80 accessory power receptacle - 110 V AC.
