2. TROUBLE DIAGNOSIS TEST
Shift Motor Test
1. Check short and open circuit before and during shifting.
2. When the system detects a fault in the shift motor for over 1 second, the “4WD CHECK” warning lamp comes on
and a trouble code is stored into memory.
3. The trouble code being detected in shift motor during its operation is defined as timeout.
4. The trouble code for the shift motor can be erased by using scanner.
Transmission System Timeout Test
1. The shift timeout occurs when the position sensor of shift motor does not try to operate, which happens 1.5
seconds after completion of 2H-4H shift and 3 seconds after completion of 4H-4L shift.
2. When the timeout occurs, TCCU cuts off the voltage to shift motor and operates the compensation mode.
Position Encoder Test
1. When the system detects a fault in shift motor for over 1 second, the “4WD CHECK” warning lamp comes on and
the trouble code is stored into the memory.
2. The position encoder fault can be divided into a general encoder fault and short to ground of position encoder
circuit.
1) General encoder fault: Invalid position code input
2) Short to ground of position encoder circuit: Ground for encoder circuit
Clutch Coil Test
1. Check the clutch coil for open and short circuit.
2. When the system detects a fault in shift motor for over 0.8 seconds, the “4WD CHECK” warning lamp comes on
and the trouble code is stored into the memory.
