Frequently asked questions about U0236

What does U0236 mean?

Lost Communication With Column Lock Module. The control module stopped receiving expected network messages from the Column Lock Module node on the vehicle communication bus.

Is U0236 generic or manufacturer-specific?

U0236 is a generic OBD-II code: it has the same meaning on every make and model that follows the SAE standard.

Can TuningBot remove U0236 at file level?

Not guaranteed. Powertrain (P) codes can be reliably disabled in the ECU calibration, but body, chassis and network codes depend on the specific control unit and how the fault is implemented - some can be handled, some cannot. Ask for a quote and our engineers will check your file and tell you, free of charge, whether U0236 is removable in your case.
