What Does U0206 Mean?
The body control module or gateway has lost network communication with the folding top (convertible roof) control module. This prevents proper operation of the convertible top system and may disable its functionality entirely.
Common Causes
40%
Failed folding top control module with internal component failure
25%
Corroded or damaged electrical connector at the folding top control module
20%
Open or short circuit in CAN bus wiring to folding top module
10%
Loss of power or ground to the folding top control module
5%
Body control module or gateway communication failure
Diagnostic Steps
1
Step 1: Locate the folding top control module (usually in trunk area or behind rear seats) and verify power and ground at connector
2
Step 2: Inspect the module connector for water intrusion, corrosion, or bent pins, especially if module is in trunk area
3
Step 3: Check CAN bus communication lines for continuity and proper resistance between folding top module and body control module
4
Step 4: Monitor live data with scan tool to verify if module is receiving commands but not responding
5
Step 5: If all wiring checks pass, replace folding top control module and reprogram/initialize as needed
Estimated Repair Cost

Parts + labor, varies by vehicle and location
The body control module or gateway has lost network communication with the folding top (convertible roof) control module. This prevents proper operation of the convertible top system and may disable its functionality entirely.
The most common cause of U0206 (Lost Communication With Folding Top Control Module) is: Failed folding top control module with internal component failure
Typical repair costs for U0206 range from $200 to $1,200, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Not a safety concern for driving, but convertible top will likely be inoperable. Ensure top is fully closed and secured before driving if malfunction occurs while top is open.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to U0206 to identify the root cause.
