A gearbox warning or flashing selector display means the control system has detected an operating condition outside its permitted range. Protective mode may restrict gears or disengage a clutch to reduce damage.
What To Do
- Do not repeatedly clear the faults before diagnosis.
- Record when the warning appears and whether cycling the ignition changes it.
- Avoid continued driving if the vehicle loses drive, overheats, makes abnormal mechanical noise or cannot select gears safely.
- Arrange a diagnostic assessment that reads the fault environment and related vehicle systems.
The code description alone may identify the affected circuit or operating condition, but additional tests are normally required to identify the failed component.
