U0206 Lost Communication With Folding Top Control Module

Check engine lightUsually off
EmissionsNot relevant
Drive cycleNot required
Limp modeNo

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.

Likely causes

Module software needs an update after programming (Lamborghini Revuelto)
Fuse, power or ground of the top module missing
Harness or connector in the top compartment damaged or wet
Folding top module faulty

Symptoms

  • Convertible top neither opens nor closes
  • Roof or top warning in the instrument cluster
