Without Accessory Shock Sensor
- Ignition OFF, disconnect the harness connector at the inclination sensor.
- Ignition ON, verify a test lamp illuminates between the B+ circuit terminal 1 and ground.
- If the test lamp does not illuminate, test the B+ circuit for a short to ground or an open/high resistance.
- Test for B+ between the signal circuit terminal 3 and ground.
- If not the specified value, test the signal circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the BCM.
- Ignition OFF, connect the harness connector at the inclination sensor. Disconnect the X7 harness connector at the BCM.
- Ignition ON, test for B+ between the signal circuit terminal 15 and ground.
- If not the specified value, test the signal circuit for a short to ground or and open/high resistance. If the circuit tests normal, replace the inclination sensor.
- If all circuits test normal, test or replace the inclination sensor.
With Accessory Shock Sensor
- Ignition OFF, disconnect the harness connector at the inclination sensor and the harness connector at the shock sensor.
- Ignition ON, verify a test lamp illuminates between the inclination sensor B+ circuit terminal 1 and ground.
- If the test lamp does not illuminate, test the B+ circuit for a short to ground or an open/high resistance.
- Test for B+ between the signal circuit terminal 3 and ground.
- If not the specified value, test the signal circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the BCM.
- Ignition OFF, connect the harness connector at the inclination sensor. Disconnect the X7 harness connector at the BCM.
- Ignition ON, test for B+ between the BCM signal circuit terminal 15 and ground.
- If not the specified value, test the signal circuit for a short to ground or and open/high resistance. If the circuit tests normal, test or replace the inclination sensor.
- Ignition OFF, connect the harness connector at the shock sensor.
- Ignition ON, test for B+ between the BCM signal circuit terminal 15 and ground.
- If not the specified value, test or replace the shock sensor.
- If all circuits test normal, test or replace the inclination sensor.

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