IMPORTANT:
When removing connectors, inspect for damage or corrosion. Damage or corrosion to the following requires repair or replacement of the affected component/connector:
- Passenger seat belt tension sensor
- Passenger presence module
- Passenger seat belt tension sensor wiring harness connector
- Passenger presence module wiring harness connector
- Ignition OFF, disconnect the X2 harness connector at the passenger seat belt tension sensor.
- Ignition ON, test for 4.5-5.5 volts between the voltage reference circuit terminal B X2 and ground.
- If less that the specified range, test the voltage reference circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the passenger presence module.
- If greater that the specified range, test the voltage reference circuit for a short to voltage. If the circuit tests normal, replace the passenger presence module.
- Ignition OFF, remove the AIRBAG fuse. Test for less than 3 ohms between the low reference circuit terminal A X2 and ground.
- If greater than the specified range, test the low reference circuit for open/high resistance. If the circuit tests normal, replace the passenger presence module.
- Ignition OFF, disconnect the harness connector at the passenger presence module.
- Test for infinite resistance between the signal circuit terminal 4 and ground.
- If less than the specified value, test the signal circuit for a short to ground.
- Ignition ON, test for less than 1 volt between the signal circuit terminal 4 and ground.
- If greater than the specified range, test the signal circuit for a short to voltage.
- Test for less than 1 ohm between the signal terminal 4 and circuit terminal C X2 at the sensor harness connector.
- If greater than the specified range, test the signal circuit for an open/high resistance.
- If all circuits test normal, replace the seat belt buckle.
IMPORTANT:
The AIRBAG fuse that supplies ignition voltage must be removed to ensure the passenger presence module is inactive. An active passenger presence module may cause inaccurate resistance readings.

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.
