Circuit/System Description
The B174W Frontview Camera - Windshield performs a self-test to verify if a malfunction exists within the system. During the power-up mode, the B174W Frontview Camera - Windshield also checks for a valid calibration data set. If a malfunction or invalid calibration data is detected within the system, the Service Front Camera message will be displayed on the driver information center.
The Service Front Camera message is also displayed when the K124 Active Safety Control Module is not communicating with the instrument cluster on the low speed GMLAN serial data bus.
