1. Accessory DC/AC Power Inverter Module Always OFF

2. Accessory DC/AC Power Inverter Module Always ON



Circuit/System Description

The accessory DC/AC power inverter module converts 12 V direct current (DC) battery voltage to 220-230 V at 50 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 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 inverter module detects the voltage from the accessory power receptacle switch, the inverter module begins to supply 220-230 V AC to the accessory power receptacle - 220V AC after a 1.5 second delay.

Circuit/System Verification


1. Ignition ON, connect the AC extension lead to the X81B accessory power outlet 220V AC. When plugging in the extension lead to the X81B accessory power outlet 220V AC, the T1 DC/AC converter accessory is turned ON.

2. Test for 220-230 V AC between the terminals at the extension cord.

3. Test for 49-51 Hz AC across the line A and line B terminals of the extension cord.


Circuit/System Testing


1. Ignition OFF, nothing plugged into the X81B accessory power receptacle - 220V AC, disconnect the harness connectors at the appropriate T1 accessory DC/AC power inverter module.

2. Scan tool disconnected, open and close the driver door and wait 1 minute. Test for less than 5 Ω between the ground circuit terminal 11 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 6 and ground.

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

6. Test for less than 1.0 V between the signal circuit terminal 12 and ground.

7. If greater than the specified value, test the signal circuit for a short to voltage. If the circuit tests normal, test or replace the X81B accessory power receptacle - 220V AC.

8. Test for infinite resistance between the signal circuit terminal 12 and ground.

9. If less than the specified value, test the signal circuit for a short to ground.

10. Test for less than 1.0 V between the AC circuit terminals listed below and ground.

• AC Terminal 2

• AC Terminal 3

• AC Terminal 7

11. If greater than the specified value, test the AC circuit for a short to voltage. If the circuit tests normal, test or replace the X81B accessory power receptacle - 220V AC.

12. Test for infinite resistance between the AC circuit terminals listed below and ground:

• AC Terminal 2

• AC Terminal 3

• AC Terminal 7

13. If less than the specified value, test the AC circuit for a short to ground.

14. Test for less than 5 Ω between the AC circuit terminals listed below:

• X81B accessory power receptacle - 220V AC terminal 3 X1 and the T1 accessory DC/AC power inverter module terminal 2.

• X81B accessory power receptacle - 220V AC terminal 3 X1 and the T1 accessory DC/AC power inverter module terminal 3.

• X81B accessory power receptacle - 220V AC terminal 3 X2 and the T1 accessory DC/AC power inverter module terminal 7.

15. If greater than the specified range, test the appropriate AC circuit for an open/high resistance. If the circuit tests normal, test or replace the X81B accessory power receptacle - 220V AC.

16. Disconnect the harness connector at the X81B accessory power receptacle - 220V AC.

17. Ignition ON, verify that a test lamp illuminates between the ignition voltage circuit terminal 1 X1 and ground.

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

19. Ignition OFF, connect the harness connector at the X81B accessory power receptacle - 220V AC.

20. Connect an AC powered device to the X81B accessory power receptacle - 220V AC.

21. Ignition ON, verify that a test lamp illuminates between the T1 accessory DC/AC power inverter module control circuit terminal 12 and ground.

22. If the test lamp does not illuminate, test the control circuit for an open/high resistance. If the circuit tests normal, test or replace the X81B accessory power receptacle - 220V AC.

23. If all circuits test normal, replace the T1 accessory DC/AC power inverter module.


Component Testing


Accessory Power Outlet

1. Ignition OFF, remove the X81B accessory power receptacle - 220V AC.

2. Test for greater than 1 M Ω between terminal 3 X2 and terminal 3 X1.

3. If less than the specified range, replace the X81B accessory power receptacle - 220V AC.

4. Test for less than 3 Ω between the following terminals:

• The terminal 3 X2 and the applicable receptacle terminal

• The terminal 3 X1 and the applicable receptacle terminal

5. If greater than the specified range, replace the X81B accessory power receptacle - 220V AC.

6. Test for infinite resistance between terminal 1 X1 and terminal 1 X2.

7. If not the specified value, replace the X81B accessory power receptacle - 220V AC.

8. Connect an AC powered device to the X81B accessory power receptacle - 220V AC.

9. Test for less than 3 Ω between terminal 1 X1 and terminal 1 X2.

10. If greater than the specified range, replace the X81B accessory power receptacle - 220V AC.
