2010 Cadillac Truck SRX AWD V6-2.8L Turbo Page 404
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.
