WARNING: This page is about a different car, the 2007 Buick Lucerne. However, it is still accessible from the selected car via links, so may be relevant.
IMPORTANT: When removing connectors inspect for damage or corrosion. Damage or corrosion in the following requires repair or replacement of the affected component/connector.
  • The rear object sensors.
  • The object alarm module.
  • The rear object sensor wiring harness connector.
  • The object alarm module wiring harness connector.
  1. Ignition OFF, disconnect the harness connector of the suspect rear object alarm sensor.
  2. 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.
  3. 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.
  4. 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.
  5. 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.
