DTC C1A21 Object Recognition Camera: Description

WARNING: This page is about a different car, the 2008 Lexus LS 600hL. However, it is still accessible from the selected car via links, so may be relevant.

The driving support ECU uses the front millimeter wave radar sensor, driver monitor camera and object recognition camera to detect obstacles in front of and behind the vehicle, and detect the direction that the driver's head is facing. Based on this information, the driving support ECU sends pre-collision control operation signals.

If the driving support ECU detects a malfunction in the object recognition camera, DTC C1A21 is output.
