(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

DLN-59

.

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

DLN-83

.

15

Power supply

Power supply voltage for transfer control unit is abnormally
low while driving.

Refer to

DLN-28

.

16

4WD shift switch

More than two switch inputs are simultaneously detected
due to short circuit of 4WD shift switch.

Refer to

DLN-38

.

17

(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

DLN-84

.

18

Wait detection switch

Improper signal from wait detection switch is input due to
open or short circuit.

Refer to

DLN-42

.

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

DLN-46

.

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

DLN-52

.

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

DLN-55

.

22

• If ABS operation signal, VDC operation signal or TCS operation signal is displayed, first perform the trouble diagnosis for

ABS system.

• If Output shaft revolution signal is displayed, first perform the trouble diagnosis for A/T system.
NOTE:

• If actuator position switch or actuator circuit is displayed, first erase self-diagnostic results. (Actuator position switch or actuator circuit

may be displayed after installing transfer control unit or transfer assembly.)

• If clutch pressure switch or line pressure switch is displayed only while driving in reverse, check the continuity of R position on trans-

mission range switch. When there is no malfunction found in the electrical system, check the hydraulic system.
