U053C: Invalid Image Data from Module B
Diagnostic trouble code U053C indicates that the electronic control module responsible for processing images (such as rearview cameras, night vision, or driver assistance systems) has received invalid or erroneous data from a designated image processing sub-module B. This fault occurs at the CAN (Controller Area Network) or LIN communication layer between modules. The receiving module detects an inconsistency in the data frame—due to electrical noise, packet interruption, or a logical fault in the transmitting module—causing the image information to be discarded because it does not meet expected integrity parameters.
1. Commonly Affected Makes
This is a generic OBD2 code, potentially applicable to any manufacturer using this diagnostic standard.
2. Most Common Causes
- Faulty or damaged image processing module B
- Short circuit or open circuit in the communication bus wiring
- Corroded connectors or loose terminals in the camera or module harness
- Power supply failure (voltage out of range) to module B
- Electromagnetic interference (EMI) affecting data transmission
- Module software needs reprogramming or update
3. Symptoms You Will Notice
- Rearview camera or night vision display shows no image or distorted image
- Driver assistance systems (e.g., lane departure warning) malfunction or become inoperative
4. Step-by-Step Diagnosis
Scan for all stored codes and freeze frame data to confirm U053C
Inspect wiring and connectors for damage, corrosion, or looseness
Check power and ground circuits to module B for proper voltage
Test communication bus for shorts, opens, or excessive noise
If no physical issues found, attempt to reprogram or update module B software
Replace module B if all other checks pass
5. Frequently Asked Questions
Is it safe to drive?▼
Yes, it is generally safe to drive, but some driver assistance features may not work properly. Have the issue diagnosed soon to restore full functionality.
How much does it cost to fix?▼
The cost can range from $100 to $600 depending on the root cause. Simple wiring repairs may be under $200, while module replacement can exceed $500.
