Diagnostic Aids

The frontview camera module disable history buffers are used to store information about the frontview camera module features that are disabled. The buffers will only update if the disable condition changes.

For example, if the data received from the steering wheel angle sensor is Invalid across many ignition cycles, it will only appear in one history buffer and not all history buffers. If the condition is the current reason why the frontview camera module is disabled, it will be identified in the Frontview Camera Disable History 1 parameter. If a new disable condition occurs, such as vehicle speed validity is invalid, the invalid steering wheel angle sensor fault will shift into the Frontview Camera Disable History 2 parameter and vehicle speed validity invalid will be in Frontview Camera Disable History 1 parameter. Since there are only four disable history buffers, the invalid steering wheel angle sensor will be cleared from the disable buffer if four other disable reasons occur since the last invalid steering wheel angle sensor event occurred. The Frontview Camera Disable History 1 parameter contains the current reason that one of the frontview camera module features is disabled.

The Frontview Camera Disable History parameters can display the following values:

Lane Departure Warning Indicator Malfunction
Lane Departure Warning Switch Malfunction
Camera Obstructed
Accelerator Pedal Position Out of Range
Driven Wheel Speed Signal Invalid
Non-Driven Wheel Speed Signal Invalid
Brake Pedal Moderate Travel Signal Invalid
Brake Pedal Initial Travel Position Achieved

Invalid Data Received From Steering Wheel Angle Sensor Module
Forward Collision Alert Switch Malfunction
Clutch Pedal Position (CPP) Sensor Performance
Transmission Gear Engaged
Acceleration Sensor Longitudinal Signal
Invalid Data Received From Yaw Rate Sensor Module
Power Mode Controlled by Backup Device
System Power Mode
