Symptoms

  • Multiple warning lamps possible
  • Functions of the affected module unavailable

Possible causes

  • CAN bus wiring fault (open, short, chafed harness)
  • Faulty control module loading the bus
  • Connector or terminal corrosion

Recommended checks

  • Perform a full-module scan to map which modules communicate

Frequently asked questions about U0127

What does U0127 mean?

Lost Communication With tire pressure monitor module. The control module stopped receiving expected network messages from the tire pressure monitor module node on the vehicle communication bus.

Is U0127 generic or manufacturer-specific?

U0127 is a generic OBD-II code: it has the same meaning on every make and model that follows the SAE standard.

Can TuningBot remove U0127 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 U0127 is removable in your case.
