Circuit/System Verification
Ignition ON, transmission in REVERSE, verify that the scan tool Sensor Voltage Feed Output parameter is 7.2-9.2 volts.
Circuit/System Testing
1. Ignition OFF, disconnect the harness connector at each of the object alarm sensors.
2. Ignition ON, verify DTC B1E3A is not set as current.
瀚慖f DTC is set, test the 8 V reference circuit terminal 1 for a short to voltage, short to ground, or an open/high resistance. If circuit tests
normal, replace the rear object sensor control module.
3. Install each sensor harness connector one at a time, checking DTCs after each sensor is connected. Verify DTC B1E3A is not set as current.
瀚慖f DTC is set, replace the object alarm sensor that was connected immediately before the DTC set.
