[TRANSFER: ATX14B]
TRANSFER CONTROL UNIT
CAUTION:
• If CAN communication is displayed with other DTCs, first perform the trouble diagnosis for CAN communication line.
10
Neutral-4LO switch
Improper signal from neutral-4LO switch is input due to
open or short circuit.
11
Clutch pressure switch
• Improper signal is input due to open or short circuit.
• Malfunction occurs in clutch pressure switch or hydraulic
circuit.
12
Line pressure switch
• Improper signal is input due to open or short circuit.
• Malfunction occurs in line pressure switch or hydraulic
circuit.
Refer to
13
Engine speed signal
(from ECM)
• Malfunction is detected in engine speed signal that is out-
put from ECM through CAN communication.
• Improper signal is input while driving.
Refer to
14
Accelerator pedal posi-
tion sensor (from
ECM)
• Malfunction is detected in accelerator pedal position sig-
nal that is output from ECM through CAN communication.
• Signal voltage from accelerator pedal position sensor is
abnormally high or low.
Refer to
15
Power supply
Power supply voltage for transfer control unit is abnormally
low while driving.
Refer to
16
4WD shift switch
More than two switch inputs are simultaneously detected
due to short circuit of 4WD shift switch.
Refer to
17
ABS operation signal
(from ABS)
Malfunction is detected in ABS operation signal that is out-
put from ABS actuator and electric unit (control unit)
through CAN communication.
Refer to
18
Wait detection switch
Improper signal from wait detection switch is input due to
open or short circuit.
Refer to
19
Actuator motor
• Motor does not operate properly due to open or short cir-
cuit in actuator motor.
• Malfunction is detected in the actuator motor. (When
4WD shift switch is operated and actuator motor is not
operated)
• Malfunction is detected in transfer shift high relay and
transfer shift low relay.
Refer to
20
Actuator position
switch
• Improper signal from actuator position switch is input due
to open or short circuit.
• Malfunction is detected in the actuator position switch.
Refer to
21
Actuator circuit
• Transfer control device actuator circuit is shorted or open.
(Malfunctions are detected when motor relay circuit is
open/shorted or relay transfer shift circuit is open/short-
ed.)
• Malfunction occurs in transfer control device drive circuit.
Refer to
22
VDC operation signal
(from VDC)
Malfunction is detected in VDC operation signal that is out-
put from ABS actuator and electric unit (control unit)
through CAN communication.
Refer to
23
TCS operation signal
(from TCS)
Malfunction is detected in TCS operation signal that is out-
put from ABS actuator and electric unit (control unit)
through CAN communication.
Refer to
24
