Chevrolet Trax: DTC B1011: System disabled information stored malfunction

Diagnostic Instructions

• Perform the Diagnostic System Check - Vehicle prior to using this diagnostic procedure.
• Review Strategy Based Diagnosis for an overview of the diagnostic approach.
• Diagnostic Procedure Instructions provides an overview of each diagnostic category.

DTC Descriptor

DTC B1011 00

System Disabled Information Stored Malfunction

Circuit/System Description

The frontview camera module permanently monitors the serial data bus for error messages. When a malfunction is detected by the frontview camera module, the system will be disabled and an error message will be stored in the frontview 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
• Frontview camera enabled

Conditions for Setting the DTC

The frontview camera module detects a malfunction.

Action Taken When the DTC Sets

• The frontview camera module is disabled.
• The frontview 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 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.

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 frontview camera module is disabled then it will be set in frontview 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. Frontview camera module disable history buffer 1 contains the current reason that one of the frontview camera module features is disabled.

The frontview camera module disable history buffers 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
• 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

NOTE: Do not replace K109 Frontview Camera Module for this DTC. DTC B1011 is an information DTC.

1. gnition ON.
2. Verify no other DTC is set except for DTC B1011.

• If any other DTCs are set

Diagnose those first. Refer to Diagnostic Trouble Code (DTC) List - Vehicle .

• If no other DTCs are set

NOTE: When referring to Frontview Camera Disable History, some items such as Non-Driven Wheel Speed Signal Invalid and Driven Wheel Speed Signal Invalid may routinely be stored without B1011 being set. If B1011 has not set, disregard any information stored in the buffers as it is not indicative of a problem.

3. Refer to Diagnostic Aids and Frontview Camera Disable History for what caused B1011 to set. Diagnose the system that set the malfunction

Repair Instructions

Perform the Diagnostic Repair Verification after completing the repair.
