Frequently asked questions about U0180

What does U0180 mean?

Lost Communication With automatic lighting control module. The control module stopped receiving expected network messages from the automatic lighting control module node on the vehicle communication bus.

Is U0180 generic or manufacturer-specific?

U0180 is a generic OBD-II code: it has the same meaning on every make and model that follows the SAE standard.

Can TuningBot remove U0180 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 U0180 is removable in your case.
