- Ignition OFF, disconnect the harness connector at the T1 Accessory DC/AC Power Inverter Module.
- Test for less than 10 Ξ© between the ground circuit terminal 11 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 6 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 2
- Terminal 7
- If greater than the specified range, test the AC circuit for a short to voltage.
- Ignition OFF, wait for 1 min. Test for infinite resistance between the AC circuit terminals listed below and ground:
- Terminal 2
- Terminal 7
- If less than the specified value, test the AC circuit for a short to ground.
- Disconnect the harness connectors at the X81 Accessory Power Receptacle - 110 V AC.
- Ignition ON, verify a test lamp illuminates between the control circuit terminal 1 X1 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 Body Control Module.
- Verify a test lamp does not illuminate between the signal terminal 1 X2 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 1 X1 and the signal terminal 1 X2.
- Ignition ON, verify that a test lamp illuminates between the T1 Accessory DC/AC Power Inverter Module signal circuit terminal 12 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 connector 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 X1 and 3 X2.
- 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.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- β’ You smell fuel, burning insulation, or see smoke.
- β’ Brakes feel soft, pull hard to one side, or make grinding noises.
- β’ The engine overheats, stalls repeatedly, or misfires under load.
- β’ You are missing required tools, torque specs, or safe lifting equipment.
- β’ You are not confident in the next step or safety outcome.
