C1C6B0A - C1C6B0A MPC Camera Temporary Blind
C1C6B0A MPC Camera Temporary Blindness - Technical Diagnosis Explanation
Fault Depth Definition
DTC C1C6B0A (MPC Camera Temporary Blindness) signifies a transient interruption in the Multi-function Video Controller System during image signal transmission and processing. The core function of this fault code is to monitor whether the camera's visual perception capability has been lost, indicating the system is in a "blind" state. In this context, the image stream continuously received by the control unit experiences unrecoverable interruptions or data loss, preventing the Advanced Driver Assistance Systems (ADAS) or Rearview Camera Module from acquiring key physical environment information. This definition clarifies that the fault occurs within the real-time feedback loop between the control unit and the camera sensor, representing a key stability indicator of the video signal link.
Common Fault Symptoms
When the Multi-function Video Controller System determines that DTC C1C6B0A fault has occurred, the vehicle's electronic instrument panel and functional modules will exhibit the following perceptible states:
- Dashboard Display Anomaly: The Driver Information Center may illuminate warning indicator lights related to the camera or video system.
- Visual Signal Loss: The corresponding real-time image area on the center screen (e.g., Rearview Image) may appear black or show no image feedback.
- Functional Degradation Notification: Related Advanced Driving Assistance functions may be temporarily disabled due to lack of visual input, accompanied by corresponding text prompts.
Core Fault Cause Analysis
Based on existing raw data, the analysis of fault root causes strictly follows the following dimensions, focusing primarily on the internal state of the control unit:
- Hardware Component Internal Stability: The fault points directly to physical state anomalies within the Multi-function Video Controller itself, involving instability in the controller chip or internal storage units during operation.
- Logic Operation and Control Strategy: As the core data processing node, the Multi-function Video Controller may experience misjudgments in image signal verification algorithms, or the system's internal watchdog timer triggers a reset mechanism.
- Functional Failure Correlation Analysis: Although raw data only explicitly states "Multi-function Video Controller Fault", this fault encompasses the logic operation level of the aforementioned hardware components, meaning that control unit is unable to maintain normal image decoding and signal forwarding tasks at specific moments.
Technical Monitoring and Trigger Logic
The judgment mechanism for this fault code is based on strict time windows and environmental condition logic. The system dynamically evaluates via the following parameters:
- Monitoring Target: The system continuously monitors whether valid image signals from the camera exist. The core metric is the integrity of video frames or the continuity of signal voltage/data packets.
- Numerical Thresholds and Ranges:
- Fault Confirmation Condition: System determines fault setting conditions are met when image loss duration exceeds $180\text{s}$ (seconds).
- Activation Trigger Condition: Monitoring logic is initiated only when the vehicle travel speed is greater than $5\text{kph}$.
- Specific Operating Condition Judgment: This fault is recorded only under dynamic vehicle driving conditions. When vehicle speed is below $5\text{kph}$, the system will not record or illuminate the fault light to prevent transient signal fluctuations during vehicle stops (e.g., parking) from being misreported as permanent blindness. Only when image signal interruption duration meets the above time threshold during vehicle travel will the fault code be formally stored and activated.
