- Ignition OFF, disconnect the harness connector at the safing sensor and the harness connector at the PIDS module.
- Test for infinite resistance between the safing sensor signal circuit terminal 1 and ground.
- If less than infinite resistance, test the circuit for a short to ground.
- Ignition ON, test for less than 1 volt between the safing sensor signal circuit terminal 1 and ground.
- If greater than the specified range, test the circuit for a short to voltage.
- Ignition ON, test for less than 1 volt between the safing sensor low reference circuit terminal 2 and ground.
- If greater than the specified range, test the circuit for a short to voltage.
- Test for less than 1 ohm of resistance between the safing sensor low reference circuit terminal 2 and the PIDS module terminal 31.
- If greater than the specified value, test the circuit for an open/high resistance. If the circuit tests normal, replace the safing sensor.
- Test for less than 1 ohm of resistance between the safing sensor signal circuit terminal 1 and the PIDS module terminal 30.
- If greater than the specified value, test the circuit for an open/high resistance. If the circuit tests normal, replace the safing sensor.
- If all circuits test normal, replace the safing sensor.
- With a scan tool, clear DTCs.
- Verify DTC B009D is not set.
- If DTC is set, replace the PIDS module.

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.
