Diagnostic Fault Information
Circuit/System Description
The accessory DC/AC power control module converts 12 V direct current (DC) battery voltage to 110-120 V alternating current (AC) in order to operate AC powered devices. The accessory DC/AC power control module provides up to 150 watts of power. The accessory DC/AC power control module is connected to a chassis ground circuit and receives fuse protected battery voltage.
The accessory power receptacle has an internal switch, that detects when an AC powered device is plugged into the receptacle. When the ignition is ON and an AC powered device is plugged into the accessory power receptacle, the normally open switch in the accessory power receptacle, closes. When the accessory DC/AC power control module detects the voltage from the accessory power receptacle switch, the control module begins to supply 110-120 V AC to the accessory power receptacle - 110V AC after a 1.5 s delay.

Circuit/System Verification
1. Ignition ON.
2. Connect an AC powered device to the Accessory Power Receptacle - 110V AC.
3. Verify the Accessory DC/AC Power Control Module is turned ON and the device works as expected.
• If the device is not powered
Refer to Circuit/System Testing.
• If the device is powered
4. All OK.
Circuit/System Testing
Warning
To help avoid personal injury, always treat the accessory power receptacle, accessory DC/AC power inverter module, AC circuit wires, and connectors as if AC high-voltage is present.
1. Ignition OFF, scan tool disconnected, ignition key removed. Wait for 2 min. Nothing plugged into the Accessory Power Receptacle - 110V AC, disconnect the harness connector at the Accessory DC/AC Power Control Module.
2. Test for less than 10 ohms between the ground circuit terminal 11 and ground.
• If greater than 10 ohms
1. Ignition OFF.
2. Test for less than 2 ohms in the ground circuit end to end.
• If 2 ohms or greater, repair the open/high resistance in the circuit.
• If less than 2 ohms, repair the open/high resistance in the ground connection.
• If less than 10 ohms
3. Verify that a test lamp illuminates between the B+ circuit terminal 6 and ground.
• If the test lamp does not illuminate and the circuit fuse is good
1. Ignition OFF.
2. Test for less than 2 ohms in the B+ circuit end to end.
• If greater than 2 ohms, repair the open/high resistance in the circuit.
• If less than 2 ohms, verify the fuse is not open and there is voltage at the fuse.
• If the test lamp does not illuminate and the circuit fuse is open
1. Ignition OFF.
2. Test for infinite resistance between the B+ circuit terminal 6 and ground.
• If less than infinite resistance, repair the short to ground on the circuit.
• If infinite resistance, replace the Accessory DC/AC Power Control Module.
• If the test lamp illuminates
4. Test for less than 1 V between the signal circuit terminal 12 and ground.
• If greater than 1 V
Repair the short to voltage in the signal circuit.
• If less than 1 V
5. Test for infinite resistance between the signal circuit terminal 12 and ground.
• If less than infinite resistance
Repair the short to ground in the signal circuit.
• If infinite resistance
6. Test for less than 1 V between the AC circuit terminals listed below and ground.
* AC Terminal 2
* AC Terminal 7
• If greater than 1 V
Repair the short to voltage in the AC circuit.
• If less than 1 V
7. Test for infinite resistance between the AC circuit terminals listed below and ground:
* AC Terminal 2
* AC Terminal 7
• If less than infinite resistance
Repair the short to ground in the AC circuit.
• If infinite resistance
8. Disconnect X1 and X2 harness connectors at the Accessory Power Receptacle - 110V.
9. Test for less than 2 ohms between the AC circuit terminals listed below:
* Accessory Power Receptacle - 110V AC terminal 3 X1 and the Accessory DC/AC Power Control Module terminal 2.
* Accessory Power Receptacle - 110V AC terminal 3 X2 and the Accessory DC/AC Power Control Module terminal 7.
• If greater than 2 ohms
Repair the open/high resistance in the AC circuit.
• If less than 2 ohms
10. Ignition ON.
11. Verify that a test lamp illuminates between the ignition voltage circuit terminal 1 X1 and ground.
• If the test lamp does not illuminate
1. Ignition OFF, disconnect the X7 harness connector at the K9 Body Control Module.
2. Test for infinite resistance between the control circuit terminal 2 X7 and ground.
• If less than infinite resistance, repair the short to ground on the circuit.
• If infinite resistance
3. Test for less than 2 ohms in the control circuit end to end.
• If 2 ohms or greater, repair the open/high resistance in the circuit.
• If less than 2 ohms, replace the K9 Body Control Module.
• If the test lamp illuminates
12. Ignition OFF, connect all harness connectors at the Accessory Power Receptacle - 110V AC. Connect a 110 V extension cord without a connected device to the Accessory Power Receptacle - 110V AC, ignition ON.
13. Verify that a test lamp illuminates between the Accessory DC/AC Power Control Module signal circuit terminal 12 and ground.
• If the test lamp does not illuminate
1. Ignition OFF.
2. Test for less than 2 ohms in the signal circuit end to end.
• If greater than 2 ohms, repair the open/high resistance in the circuit.
• If less than 2 ohms, replace the Accessory Power Receptacle - 110V AC.
• If the test lamp illuminates
14. Test or replace the Accessory DC/AC Power Control Module.
Component Testing
Accessory Power Outlet 110V AC
1. Ignition OFF, disconnect the harness connectors at the Accessory Power Receptacle - 110V AC.
2. Connect positive DMM lead to terminal 3 X2 and negative DMM lead to terminal 3 X1. Test for infinite resistance.
• If less than infinite resistance
