How to restore the malfunction warning of the Toyota pre-collision system.

Model: Toyota Toyota Various
Part: Warning light – error code

Video tutorial

Today we will explain how to reset the malfunction warning of the pre-collision system of the Toyota. To solve the problem: we turn off the engine, wait 10 minutes, and start the engine to check if the warning light is off. If the light has not reset, we will need to proceed differently, so we turn off the vehicle and clean the radar sensor located behind the Toyota emblem on the front grille and the camera sensor located near the rearview mirror on the windshield.

After removing dirt and any debris, we start the engine to check if the warning light has reset. If it has not reset, we make sure that the external weather conditions are not too severe to affect the system's operation; in this case, we will need to wait for clear weather to reset the sensor.

On the instrument cluster of the MG ZS, the tire pressure light that appears can be reset by inflating the tires to the correct pressure: this value will be indicated on the sticker attached to the driver's door pillar. Once the tires have been properly inflated, you can turn on the instrument cluster and navigate through the menu until you find the option that indicates tire pressure: if this screen shows the new values, the light will turn off; otherwise, you will need to drive for a few miles so that the sensors can read the new values and turn off the light afterward.
