PRE-COLLISION: PRE-COLLISION SYSTEM: U0235: Lost Communication with Cruise Control Front Distance Range Sensor
U0235 - Lost Communication with Cruise Control Front Distance Range Sensor
DESCRIPTION
The driving support ECU sends information on steering angle and steering direction to the millimeter wave radar sensor. The millimeter wave radar
sensor then sends information on the presence, distance, and relative speed of objects ahead to the driving support ECU. The driving support ECU
sends this information to the ECM and performs cruise control.

INSPECTION PROCEDURE
NOTICE:
* When replacing the millimeter wave radar sensor with a new one, make sure to perform Adjust Millimeter Wave Radar
Sensor Assembly See: Accessories and Optional Equipment/Collision Avoidance and Parking Assist Systems/Distance
Sensor/Adjustments.
* Confirm that the connector is securely connected, as a partially connected connector is suspected for the cause of this DTC.
PROCEDURE
