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.

Diagnostic Aids

For symptom byte 21 the module only runs diagnostic when the vehicle is driven greater than 40 km/h (25 MPH). Therefore, even with clean

sensor with no obstruction (i.e snow or ice melted off) drive the vehicle greater than 40 km/h (25 MPH).

The following is a list of reasons this failure type byte 21 might have set:

^ One or more of the sensors may be blocked by snow, mud, ice or debris. This might happen after going through a car wash in cold weather.

^ Silicone insulator surrounding sensor maybe missing, cut or twisted.

^ Improperly installed sensor, sensor maybe be crooked due to a tight wire harness.

^ One or more of the sensors may be scratched or the paint maybe chipped.

^ Excessive paint thickness on a sensor may cause an excessive sensor ring time. When replacing or refinishing a sensor, do not apply an

excessive amount of paint or clear coat.
