Malibu L4-2.4L (2010)
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, test for 12.0-15.0 V across the battery terminals.
‹› If no within the specified range, refer to Battery Inspection/Test (See: Testing and Inspection/Component Tests and General
Diagnostics/Battery Inspection/Test).
2. 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.
3. Verify the receptacle indicator light comes on.
4. Test for 110-120 V between the terminals at the extension cord.
5. Test for 59-61 Hz AC across the line A and line B terminals of the extension cord.
Circuit/System Testing
1. Ignition OFF, disconnect the harness connectors at the T1 Accessory DC/AC power inverter module.
2. Test for less than 10 ohm 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. 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.
5. 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.
6. Disconnect the harness connector at the X81 accessory power receptacle - 110 V AC.
7. 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.
8. 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.
9. Connect a 3 A fused jumper between the control terminal 4 and the signal terminal 1.
10. 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.
11. 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.
12. If all circuits test normal, replace the X81 accessory power receptacle - 110 V AC.
