Overview - Rearview Camera System
Familiarity with the function and operation of the rearview camera system is needed if there are customer concerns.
Function:
The rear system assists the driver during back-up driving by providing the driver with an image of the traffic situation behind the vehicle via the monitor of the radio/navigation system. The system is optional equipment.
The system switches itself on by selecting the reverse gear, even when radio/navigation system is switched off.
The rear view camera system consists of the following components:
- Rearview Camera -R189-
- Radio/Navigation Display Unit Control Module -J503-
- Steering wheel with Steering Angle Sensor -G85-
It is not permitted to install an auxiliary license plate holder for vehicles with rear view camera system because it would impair the function of the rear view camera system. License plate lights may also be impaired.
DTC recognition and display
The rearview camera system has OBD.
For troubleshooting, use the Vehicle Diagnostic Tester in the "Guided Fault Finding" function.
Small calibrations are necessary.
