Diagnostic Fault Information
Circuit/System Description
The object sensors are 3-wire sensors that are used to determine the distance between the vehicle and an object of interest. The parking assist control module supplies 8 V to the object sensors via the 8 V reference circuit and provides ground via the low reference circuit. The parking assist control module triggers the sensors in a sequential loop. After each sensor transmits, the parking assist 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
* Ignition ON
* The parking assist is activated. The activation takes place through putting in the reverse gear or through operating the park assist switch.
Conditions for Setting the DTC
B0958 01, B0959 01, B0960 01, or B0961 01
The parking assist control module has detected the voltage at the sensor circuit is greater than 11.5 V or the object sensor is not grounded.
B0958 06, B0959 06, B0960 06, or B0961 06
The parking assist control module has detected the voltage at the sensor circuit less than 0.5 V.
B0958 08, B0959 08, B0960 08, or B0961 08
The parking assist control module has received an invalid signal.
B0958 21, B0959 21, B0960 21, or B0961 21
The object sensor determines no change in the position of an object while the vehicle is in motion.
B0958 3A, B0959 3A, B0960 3A, or B0961 3A
The parking assist control module determines the wrong sensor type is installed.
Action Taken When the DTC Sets
* The parking assist is disabled.
* The driver information center displays SERVICE PARK ASSIST.
Conditions for Clearing the DTC
The condition for setting the DTC is no longer present.

Circuit/System Verification
1. Verify that DTC B1405 is not present.
• If DTC is present, refer to DTC B1405 Object Detection.
2. Verify that DTC B0958 01, B0959 01, B0960 01 or B0961 01 is not present.
• If DTC is present, check the appropriate sensor for contamination with mud, ice or snow. If no contamination is diagnosed, refer to Circuit/System Testing.
3. Verify that DTC B0958 21, B0959 21, B0960 21 or B0961 21 is not present.
• If DTC is present, check the appropriate sensor for contamination with mud, ice or snow. If no contamination is diagnosed, replace the sensor.
4. Verify that DTC B0958 3A, B0959 3A, B0960 3A or B0961 3A is not present.
• If DTC is present, replace the appropriate sensor with a sensor of correct sensor type.
5. Ignition ON, transmission in REVERSE, verify the scan tool Parking Assist System Status parameter displays Enabled.
Circuit/System Testing
Note:
Scan Tool must be disconnected for steps 1 and 2 to allow module to power down.
1. Ignition OFF for 1 min, disconnect the harness connector at the appropriate rear object sensor.
2. Test for less than 5 ohms between the low reference circuit terminal 2 and ground.
• If greater than the specified value, test the low reference circuit for an open/high resistance. If the circuit tests normal, replace the K41R Rear Parking Assist Control Module.
3. Ignition ON, activate the parking assist, test for 7.5-9.0 V between the 8 V reference circuit terminal 1 and ground.
• If less than the specified range, test the 8 V reference circuit for an open/high resistance. If the circuit tests normal, replace the K41R Rear Parking Assist Control Module.
4. Activate the parking assist, test for 7.5-9.0 V between the signal circuit terminal 3 and ground.
• If less than the specified range, test the signal circuit for an open/high resistance. If the circuit tests normal, replace the K41R Rear Parking Assist Control Module.
5. Replace the appropriate rear object sensor.
