- Ignition OFF, disconnect the harness connector of the suspect rear object alarm sensor.
- Test for less than 1.0 ohm of resistance between the low reference circuit and ground.
- If greater than 1.0 ohm, test the low reference circuit for an open/high resistance. If the circuit tests normal, replace the rear object alarm module.
- Ignition ON with the transmission in reverse, test for 8.2 V-8.8 V between the rear object alarm sensor supply voltage circuit and the low reference circuit.
- If greater than 8.8 V, test the supply voltage circuit for a short to voltage. If the circuit tests normal, replace the object alarm module.
- If less than 8.2 V, test the supply voltage circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the rear object alarm module.
- Ignition ON with the transmission in reverse, test for 7.2 V-9.2 V between the rear object alarm sensor signal circuit and the low reference circuit.
- If greater than 9.2 V, test the signal circuit for a short to voltage. If the circuit tests normal, replace the rear object alarm module.
- If less than 7.2 V, test the signal circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the rear object alarm module.
- If all circuits test normal, replace the suspect rear object alarm 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.
