DTC C1A32 Driver Monitor Image cannot be Recognized: 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.

The driver's head position information is sent via the CAN communication line from the driver monitor camera to the driver monitor ECU, and then from the driver monitor ECU to the driving support ECU
