What is the cause of the Buick fault code 136?

[William]

ode136 code indicates a parking assist system malfunction. If this issue occurs, you can try disconnecting and reconnecting the battery cables, mainly focusing on the power supply voltage issues of the assist system's radar, camera, and other wiring. Alternatively, it could be due to a faulty camera, sensor, or distance-measuring device. If any problems are detected, it is advisable to seek repairs promptly. The automatic parking assist system is designed to enable automated parking. Among various automotive accessories, those related to reversing safety are particularly noteworthy. Brand models equipped with reversing assist systems are often considered a hallmark of high-end vehicle configurations. Different automatic parking systems use various methods to detect objects around the vehicle. Some systems are equipped with sensors around the front and rear bumpers, which can act as both transmitters and receivers. These sensors send signals that reflect off obstacles around the vehicle. The onboard computer then uses the time taken to receive the signals to determine the obstacle's position. Other systems use cameras or radar installed on the bumpers to detect obstacles. However, the end result is the same: the vehicle detects parked cars, the size of the parking space, and the distance from the curb, then maneuvers the car into the parking spot.
