The shift operation is only allowed when some conditions are satisfied. These shift conditions should be satisfied for
2 seconds before starting motor. The motor has three seconds of delay at its initial operation to do trouble diagnosis.
Once the motor starts, the shift conditions are no longer checked.
Shift conditions are as follows:
1. Normal battery voltage and shift motor for all gears
2. 2H and 4H shifts has nothing to do with the vehicle speed, the “N” position in the automatic transmission or the
clutch signal.
3. The shift operation between 4H and 4L is only available when the vehicle speed is below 11 rpm or 2 kph.
Motor Controls
1. The shift steps have the sequence of 2H
→
4H
→
4L and 4L
→
4H
→
2H. TCCU operates the shift motor until it
reads the required position code. If it detects the faulty code, the system is operated with the compensation
mode.
2. Once the shift operation is started, it is completed regardless of the ignition power. If there are not operating
signals from the position sensor, the shifting failure due to timeout occurs. This failure appears when the shifting
time between 2H and 4H and between 4H and 4L is delayed over 5 seconds compared to normal shift. Once the
shifting time exceeds the specified time, TCCU cannot properly supply the voltage to shift motor and is operated
in compensation mode.
3. Even though the system recognizes a fault before motor starts, it is considered as a fault.
4. Motor stops operation when it reaches target range.
Synchronization
Synchronization occurs during shifting from 2WD (2H) to 4WD (4H or 4L). The synchronizer clutch and the hub
solenoid are controlled during the synchronization as follows:
1. The clutch coil operates when the selector changes from 2H to 4H/4L.
2. The shift motor moves in 4H mode.
3. The hub solenoid starts its operation 4 seconds after shifted to 4H.
4. The clutch coil stops its operation 5 seconds after the hub solenoid is activated.
Compensation
The motor stops when the encoder related to troubles are detected during shift operation. It moves toward LOW-
HIGH direction for 5 seconds so that the motor is not left in unidentified position.
