First, the control module is connected directly to the battery and Powers the sensors as well as the computer taking in all the information. Many failing control modules have dirt or grind or corrosion.
The sensor is not working – Sensors can stop working for a variety of reasons. Maybe you accidentally struck a sensor on an obstacle. Rain may have gotten into the sensor and shorted it, or it is glitching.
The computer is glitching, and it needs to be reset – the parking assist, as well as a few other assistance programs inside of Toyota, are all parts of a computer program controlled by the control module. These computer programs can glitch out like any other piece of software.
