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 .
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

1. Ignition OFF for 30 s, disconnect the harness connector at the appropriate rear object sensor.
2. Test for less than 5 Ω between the low reference circuit terminal 2 and ground.
⇒ If greater than the specified range, test the low reference circuit for an open/high resistance. If the circuit tests normal, replace the K41 Front and Rear Parking Assist Control Module.
3. Ignition ON, 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 K41 Front and Rear Parking Assist Control Module.
4. Ignition OFF, remove the malfunctioning object sensor and swap locations with another properly functioning rear object sensor. Connect the harness connector at both sensors.
5. Ignition ON, verify the DTC is set for the new location in which the malfunctioning sensor is installed.
⇒ If the DTC does not set for the new location, test the signal circuit terminal 3 for a short to voltage, short to ground, or an open/high resistance. If the circuit tests normal, replace the K41 Front and Rear Parking Assist Control Module.
6. If the DTC sets for the new location in which the malfunctioning sensor is installed, replace the appropriate rear object sensor.

Repair Instructions

Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
