What it means
A control module received invalid data from the folding top control module. The code identifies a data validity fault; the specific affected function depends on the vehicle.
How it works
The folding top control module manages the vehicle's powered convertible or folding roof and reports its status to other modules. U0507 sets when a receiving module judges data from the folding top control module invalid, which can prevent roof operation or trigger a system warning.
Common causes
Most likely first.
- Fault in the transmitting module
- Network wiring or connector fault
- Module power or ground fault
- Software or configuration mismatch
Symptoms
- The folding top may not operate correctly
- Related communication codes or system warnings may appear
How to diagnose it
- Save freeze-frame data and scan body and roof-control modules for related communication or folding-top faults before attempting to operate the roof.
- Check live data for folding-top module communication and reported roof position or operating status, comparing it with the actual roof state.
- Inspect the folding-top module's connectors and network wiring for corrosion, water intrusion, loose pins, or damage, especially in areas exposed to roof movement or moisture.
- Check the module's power and ground connections under the manufacturer's procedure, since a supply fault can make status messages invalid.
- If wiring and supply are sound, verify module software and vehicle configuration, then test the folding-top control module for internal failure.
Common fixes
- Clean, dry, and secure a loose or corroded folding-top module connector.
- Repair damaged network wiring to the folding-top control module.
- Restore a faulty power or ground connection to the module.
- Correct an applicable software or configuration mismatch.
- Replace the folding-top control module if testing confirms it is faulty.
Can I keep driving?
Avoid operating the folding top until the fault is diagnosed, since a roof that stops partway may not secure or seal correctly. If the top is not fully latched, avoid driving and follow the vehicle's instructions for securing it.
A code shows where the control module detected a fault, not always which part failed. Check the causes in order and confirm with a test before replacing parts. Have several codes? Check them together
This is a generic code: it means the same on every make. The car’s maker may add more detail in its own service information.
