Kia Carens: Automatic Transaxle System / Troubleshooting
Kia Carens RP (2013-2018) Service Manual / Automatic Transaxle System / Troubleshooting
| Troubleshooting |
| Limp Home Mode |
Features a fail-safe function that prevents dangerous situations in the event
of a transaxle failure. The vehicle will be driven in limp home mode if the
transaxle malfunctions. In this mode, the transaxle 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 as mechanical parts,
solenoid valves, TCM, CAN communication)
