TCCU SYSTEM
TCCU Initialization
• TCCU sends relevant data to meter cluster via CAN to diagnose and check the indicators when the ignition switch is
turned to ON. At this time, the 4WD indicators (4WD LOW, 4WD HIGH, 4WD CHECK) comes on for 0.6 seconds.
• If the selector switch position and the shift motor position code does not match when the IG power is turned ON, the
shift is controlled to move in the direction of the selector switch position
Interpretation of Position Sensor
- When the 4H/4L switch is operated and the position sensor recognizes the shift motor position while the system is
