Diagnostic Fault Information
Circuit/System Description
The accessory DC/AC power inverter module converts 12 V direct current (DC) battery voltage to 110 V at 60 Hertz (Hz) alternating current (AC) in order to operate AC powered devices. The accessory DC/AC power inverter module provides up to 150 watts of power. The accessory DC/AC power inverter module is connected to a chassis ground circuit and receives fuse protected battery voltage.
The accessory power receptacle - 110 V AC 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 - 110 V AC, the normally open switch in the accessory power receptacle - 110 V AC, closes. When the accessory DC/AC power inverter module detects the voltage from the accessory power receptacle - 110 V AC switch, the inverter module begins to supply 110 V AC to the accessory power receptacle - 110 V AC after a 1.5 second delay.

Circuit/System Verification
1. Ignition ON, connect an AC power extension cord to the X81 accessory power receptacle - 110 V AC. Inserting the extension cord plug into the X81 accessory power receptacle - 110 V AC turns the T1 accessory DC/AC power inverter module ON.
2. Test for 110-120 V between the terminals at the extension cord.
3. Test for 59-61 Hz AC across the line A and line B terminals of the extension cord.
Circuit/System Testing
1. Ignition OFF, nothing plugged into the X81 accessory power receptacle - 110 V AC, disconnect the harness connectors at the T1 accessory DC/AC power inverter module.
2. Test for less than 5 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.
3. 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.
4. Test for less than 1.0 V between the signal circuit terminal 2 X1 and ground.
• If greater than the specified value, test the signal circuit for a short to voltage. If the circuit tests normal, test or replace the X81 accessory power receptacle - 110 V AC.
5. Test for infinite resistance between the signal circuit terminal 2 X1 and ground.
• If less than the specified value, test the signal circuit for a short to ground.
6. 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 value, test the AC circuit for a short to voltage. If the circuit tests normal, test or replace the X81 accessory power receptacle - 110 V AC.
7. 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 signal circuit for a short to ground.
8. Test for less than 5 ohms between the terminals listed below:
* X81 accessory power receptacle - 110 V AC terminal 3 and the T1 accessory DC/AC power inverter module terminal 4 X1.
* X81 accessory power receptacle - 110 V AC terminal 6 and the T1 accessory DC/AC power inverter module terminal 6 X1.
• If greater than the specified range, test the appropriate line circuit for an open/high resistance. If the circuit tests normal, test or replace the X80 accessory power receptacle - 110 V AC.
9. Disconnect the harness connector at the X80 accessory power receptacle - 110 V AC.
10. Ignition ON, verify that a test lamp illuminates between the ignition voltage circuit terminal 4 and ground.
• If the test lamp does not illuminate, test the ignition voltage circuit for a short to ground or an open/high resistance.
11. Ignition OFF, connect the harness connector at the X80 accessory power receptacle - 110 V AC.
12. Connect an AC powered device to the X80 accessory power receptacle - 110 V AC.
13. 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 an open/high resistance. If the circuit tests normal, test or replace the X80 accessory power receptacle - 110 V AC.
14. If all circuits test normal, replace the T1 accessory DC/AC power inverter module.
Component Testing
Accessory Power Outlet
1. Ignition OFF, remove the X80 accessory power receptacle - 110 V AC.
2. 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.
3. 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.
4. Test for infinite resistance between terminal 1 and terminal 4.
• If not the specified value, replace the X80 accessory power receptacle - 110 V AC.
5. Connect an AC powered device to the X80 accessory power receptacle - 110 V AC.
6. Test for less than 3 ohms between terminal 1 and terminal 4.
• If greater than the specified range, replace the X80 accessory power receptacle - 110 V AC.
