Characteristics of TCU and Automatic Transmission (LHM: Limp-Home
Mode)
The emergency driving mode is to minimize the vehicle’s operation, which is a mode for maintaining minimum driving
condition if the automatic transmission is defective. In emergency driving mode, excessively long driving and unrea-
sonable driving should be avoided to prevent a critical fault occurence in advance.
Emergency driving mode can largely be divided in electrical defective and hydraulic pressure/mechanical defective.
Electrical defect
1. If an electrical defective occurs in transmission during driving, current shift gear position is held.
1) Shut off of various solenoid valves
2) Internal pressure in transmission increases (shift shock gets bigger when changing selector lever due to
maximized MP and SP)
3) Lockup clutch is released
2. If the shift operation cannot be activated, the driver must reset the system as follows:
1) Stop the vehicle and place the selector lever to “P” position.
2) Wait for 10 seconds after stopping the engine (release hydraulic pressure)
3) Start the engine.
4) Place the selector lever to “D” or “R” position.
Mechanical/hydraulic pressure defect
1. Characteristics that appears in the vehicle are as below:
1) Holds at 3rd gear (It can be held at proper gear if the fault occurs at 3rd gear)
2) Electrical devices operate normally and the shift shock is acceptable during shift operation.
2. If the shift operation cannot be activated, the driver must reset the system as follows:
1) Stop the vehicle.
2) Stop the engine.
3) In most cases, it is reset when the engine is started and the vehicle operate normally.
