Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Circuit/System Testing
Right Side Object Sensor Malfunction
- Ignition OFF, disconnect the harness connector at the right side object sensor.
- Test for less than 5 Ξ© between the ground circuit terminals listed below and ground:
- Terminal 5
- Terminal 6
- If greater than the specified range, test the appropriate ground circuit for an open/high resistance.
- Ignition ON, verify that a test lamp illuminates between the B+ circuit terminal 2 and ground.
- If the test lamp does not illuminate, test the B+ circuit for a short to ground or an open/high resistance.
- If all circuits test normal, replace the right side object sensor.
Left Side Object Sensor Malfunction
- Ignition OFF, disconnect the harness connector at the left side object sensor.
- Test for less than 5 Ξ© between the ground circuit terminal 5 and ground.
- If greater than the specified range, test the ground circuit for an open/high resistance.
- Ignition ON, verify that a test lamp illuminates between the B+ circuit terminal 2 and ground.
- If the test lamp does not illuminate, test the B+ circuit for a short to ground or an open/high resistance.
- Ignition OFF, disconnect the harness connector at the right side object sensor.
- Ignition ON, test for less than 1 V between the serial data circuit terminal 4 and ground.
- If greater than the specified range, test the serial data circuit for a short to ground.
- Test for infinite resistance between the serial data circuit terminal 4 and ground.
- If not the specified value, test the serial data circuit for a short to ground.
- Test for less than 2 Ξ© between the serial data circuit terminal 4 at the left side object sensor harness connector and the serial data circuit terminal 4 at the right side object sensor harness connector.
- If greater than the specified range, test the serial data circuit for an open/high resistance.
- If all circuits test normal, replace the left side object sensor.
Side Object Indicator Malfunction
- Ignition OFF, disconnect the X2 harness connector at the outside rearview mirror.
- Connect a test lamp between the control circuit terminal 4 and the low reference circuit terminal 1.
- Ignition ON, verify the test lamp briefly illuminates during the system self test.
- If the test lamp does not illuminate or remains illuminated at all time, test the control circuit and the low reference circuit for a short to voltage, short to ground, or an open/high resistance. If the circuits test normal, replace the appropriate door module.
- If all circuits test normal, test or replace the appropriate outside rearview mirror.

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