Circuit/System Verification
Ignition ON, transmission in REVERSE, observe the scan tool Sensor Feed Voltage Output parameter. The reading should be between 6.3-10.4 V.
Circuit/System Testing
1. Ignition OFF, disconnect the harness connector at each of the object sensors.
2. Ignition ON, transmission in REVERSE, test for 6.3-10.4 V between the 8 V reference circuit terminal 1 at the rear object sensor harness
connector and ground.
瀚慖f less than the specified range, test the 8 V reference circuit for a short to ground. If the circuit tests normal, replace the rear object alarm
module.
瀚慖f greater than the specified range, test the 8 V reference circuit for a short to voltage. If the circuit tests normal, replace the rear object
alarm module.
3. Install each object alarm sensor harness connector one at a time, checking DTCs after each sensor is connected. Verify DTC B1405 is not set
as current.
瀚慖f the DTC is set, replace the object alarm sensor that was connected immediately before the DTC set.
4. If all circuits test normal, replace the rear object alarm module.
Repair Instructions
Perform the Diagnostic Repair Verification (See: Verification Tests) after completing the diagnostic procedure.
* Rear Object Sensor Replacement (See: Accessories and Optional Equipment/Collision Avoidance and Parking Assist Systems/Parking
Assist Distance Sensor/Service and Repair/Rear Object Sensor Replacement)
