U0206 code meaning
Lost Communication With Folding Top Control Module
What U0206 means
U0206 indicates that the folding top control module, which drives the hydraulic or electric mechanism of a convertible roof and watches its end positions, has fallen silent on the bus. Lamborghini names U020600, stored in control unit 00C5, in its Revuelto baseline update bulletins L74X-A.11.25 (model year 2024) and L74X-A.05.25 (2025): if the entry shows up during the SVM code step, the technician adds it to the test plan and runs the guided update programming for the unit. Beyond these bulletins no maker documents the code publicly. Usual consequences are a roof that will neither open nor close and a roof warning in the cluster. Invalid data from the same module is U0507. No MIL.
U0206 at a glance
- Check engine lightUsually not
- Emissions testNot an emissions code
- Limp modeNot expected
- Repair difficultyHard
- Typical labor0.5 to 4 hours
- Clears after repairWhen cleared with a scanner
Symptoms of U0206
- Convertible top neither opens nor closes
- Roof or top warning in the instrument cluster
Common causes of U0206
- Most likelyModule software needs an update after programming (Lamborghini Revuelto)
- PossibleFuse, power or ground of the top module missing
- PossibleHarness or connector in the top compartment damaged or wet
- Less likelyFolding top module faulty
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of U0206 means
| U | Network system: communication between the control modules (CAN bus). |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 06 | The exact fault in that area. |
What to do next
- Note U0206 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about U0206
What does U0206 mean?
U0206 means "Lost Communication With Folding Top Control Module". U0206 indicates that the folding top control module, which drives the hydraulic or electric mechanism of a convertible roof and watches its end positions, has fallen silent on the bus. It is a generic code, so it means the same on every make.
Is it safe to drive with U0206?
U0206 does not normally turn on the check engine light by itself. Watch for the symptoms above and have it checked soon.
Will U0206 fail an emissions test?
U0206 is not an emissions code, so on its own it usually does not fail an emissions test. Other stored codes or a lit check engine light still can.
How hard is U0206 to fix?
Difficulty: hard. A typical repair takes 0.5 to 4 hours of work. This is a job for a workshop.
Will U0206 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
