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

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

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.
