DTC Descriptor
DTC B1011
-
System Disabled Information Stored
Circuit/System Description
The front view camera module permanently monitors the serial data bus for error messages. When a malfunction is detected by the front view camera module, the system will be disabled and an error message will be stored in the front view camera module disable history buffer which is used to store information about the front camera features that are disabled.
Conditions for Running the DTC
* Ignition ON
* Front view camera enabled
Conditions for Setting the DTC
B1011
The front view camera module detects a malfunction.
Action Taken When the DTC Sets
* The front view camera module is disabled.
* The front view camera module disable history buffer stores information why the system was disabled.
Conditions for Clearing the DTC
The condition for setting the DTC is no longer present.
Diagnostic Aids
The front view camera module disable history buffers are used to store information about the front view camera module features that are disabled. The Buffers will only update if the disable condition changes.
Example: If the data received from the steering wheel angle sensor is Invalid across many ignition cycles then it will only appear in 1 history buffer and not all history buffers. If this condition is the current reason why the front view camera module is disabled then it will be set in front view camera module disable history buffer 1. If a new reason occurs, such as vehicle speed validity is invalid, then the invalid steering wheel angle sensor fault will shift into disable history buffer 2 and vehicle speed validity invalid will be in disable history buffer 1. Since there are only 4 disable history buffers, the invalid steering wheel angle sensor will age out if 4 other disable reasons occur since the last invalid steering wheel angle sensor event occurred. Front view camera module disable history buffer 1 contains the current reason that one of the front view camera module features is disabled.
The front view camera module disable history buffers can display the following values:
* Lane Departure Warning Indicator Malfunction
* Lane Departure Warning Switch Malfunction
* Sensors 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
* Lost Communication with Steering Wheel Angle Sensor Module
* Invalid Data Received From Steering Wheel Angle Sensor Module
* Forward Collision Alert Switch Malfunction
* Clutch Pedal Position (CPP) Sensor Performance
* 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
* Overvoltage
* Undervoltage
* Undefined

Circuit/System Verification
1. Verify no DTC is set.
• If a DTC is present, diagnose this first. Refer to Diagnostic Trouble Code (DTC) List - Vehicle Diagnostic Trouble Code (DTC) List - Vehicle.
2. Verify the scan tool Front View Camera System Status parameter is NORMAL.
• If not the specified value, refer to Front View Camera Module Malfunction (UFL) Front View Camera Module Malfunction (UFL).
3. Verify the scan tool Front View Camera Calibration Status parameter is CALIBRATED.
• If not the specified value, calibrate the K109 Frontview Camera Module. Refer to Front View Camera Module Calibration Front View Camera Module Calibration.
Circuit/System Testing
Note:
Perform the Circuit/System Verification before proceeding with the Circuit/System Testing.
1. Verify the scan tool Front View Camera Module Disable History displays no current malfunction. Refer to Diagnostic Aids.
• If a current malfunction is displayed, diagnose the system that sets the malfunction.
2. If no malfunction is displayed in the Front View Camera Module Disable History, refer to Front View Camera Module Malfunction (UFL) Front View Camera Module Malfunction (UFL).
Repair Instructions
Perform the Diagnostic Repair Verification Verification Tests after completing the diagnostic procedure.
