Troubleshooting |
Limp Home Mode |
Features a fail-safe function that prevents dangerous situations in the event of a transmission failure. The vehicle will be driven in limp home mode if the transmission malfunctions. In this mode, the transmission operates at a minimal functionality level (fixed shifting, limited shifting, reverse, neutral), making it possible for the vehicle to reach a service center.
Limp Home Mode : Limited shifting Mechanical limp home mode : Fixed shifting (failure of mechanical parts, solenoid valves, TCM, CAN communication) |
