Circuit Description
WARNING: This page is about a different car, the 2004 Lexus LS 430. However, it is still accessible from the selected car via links, so may be relevant.
The distance control ECU receives information about the area in front of the vehicle from the laser sensor and then sends a brake control demand signal (deceleration demand) and diagnosis signals, such as laser sensor grime or laser sensor malfunction, to the ECM.
