REAR VEHICLE MONITORING CONTROL MODULE

id092200029900


Purpose

•  The rear vehicle monitoring control module detects vehicles approaching from behind and controls the rear vehicle monitoring system.

Function

•  The rear vehicle monitoring control module emits microwaves from the radar integrated with the rear vehicle monitoring control module to detect an oncoming vehicle's position and speed via the reflected microwaves.
Note
•  The detection ability of the rear vehicle monitoring control module has limitations. In the following cases, the detection ability may lower and the system may not operate normally.
―  The rear bumper near the rear vehicle monitoring control module has become deformed.
―  Snow, ice or mud adheres to the rear vehicle monitoring control module on the rear bumper.
―  Under bad weather conditions such as rain, snow and fog.
•  Under the following conditions, the rear vehicle monitoring control module cannot detect target objects or it may be difficult to detect them.
―  Stationary objects on a road or a road side such as small, two-wheeled vehicles, bicycles, pedestrians, animals, and shopping carts.
―  Vehicle shapes which do not reflect radar waves well such as empty trailers with a low vehicle height and sports cars.
•  Turn off the system while pulling a trailer or while an accessory such as a bicycle carrier is installed to the rear of the vehicle. Otherwise, the radio waves emitted by the radar will be blocked causing the system to not operate normally.
•  The rear vehicle monitoring control module controls the rear vehicle monitoring system based on the information from the detected approaching vehicle and following CAN signals:

CAN signal sending module

Signal name
DSC HU/CM
Yaw rate signal
Start stop unit
Turn switch signal
Instrument cluster
•  RVM switch operation signal
•  Panel light signal
TCM (ATX)
Shift lever position signal
PCM
•  Vehicle speed signal
•  Gear position signal (MTX)


RVM warning indicator light brightness level change function

•  When the rear vehicle monitoring control module receives the panel light signal from the instrument cluster, it determines that the vehicle is being driven at night or in a dark place and changes the brightness of the RVM warning indicator light.


On-board diagnostic function

•  The rear vehicle monitoring control module detects a system communication error and control module internal malfunction and outputs DTCs. For DTC details, refer to On-board Diagnostic System [rear vehicle monitoring system].


Construction

•  The control module is integrated with the radar which emits microwaves and receives the reflected waves.
•  Two control modules are positioned on the left and right sides of the body inside the rear bumper.

Operation

•  When the ignition is switched ON (engine on) and vehicle speed is 30 km/h or more, the rear vehicle monitoring control module emits microwaves from the radar and starts detection of approaching vehicles.

Detection area

•  Forward and rear directions: From B-pillar towards vehicle rear at distance of approx. 50 m {164 ft}
•  Lateral direction: Approx. 3 m {9.8 ft} for vehicle side surface
