Diagnostic Fault Information

Circuit/System Description

The object alarm sensors are 3-wire sensors that are used to determine the distance between the vehicle and an object of interest. The rear object

sensor control module supplies 8 volts to the object alarm sensors via the 8 volt reference circuit and provides ground via the low reference circuit.

The rear object sensor control module triggers the sensors in a sequential loop. After each sensor transmits, the rear object sensor control module

uses the sensor echo received through the signal circuit to calculate the distance and position of an object.

Conditions for Running the DTC

* DTC B1325 is not set

* Ignition voltage is between 9-16 volts

* Transmission in REVERSE

Conditions for Setting the DTC

B0958 01, B0959 01, B0960 01, or B0961 01

Voltage seen on the object alarm sensor signal circuit is greater than 11.5 volts or the object alarm sensor is not grounded.

B0958 06, B0959 06, B0960 06, or B0961 06

Voltage seen on the object alarm sensor signal circuit is less than 0.5 volts.

B0958 08, B0959 08, B0960 08, or B0961 08

An invalid signal is received by the rear object sensor control module.
