COMPONENT DESCRIPTION

PDIA0152E

Components

Function

Transfer control unit

Controls transfer control device and controls shifts between 2WD/4WD and 4H/4LO.

Transfer control device

Integrates actuator motor and actuator position switch.

Actuator motor

Moves shift rods when signaled by transfer control unit.

Actuator position switch

Detects actuator motor position.

Wait detection switch

Detects if transfer case is in 4WD.

4LO switch

Detects if transfer case is in 4LO.

ATP switch

Detects if transfer case is in neutral.

4WD shift switch

Allows driver to select from 2WD/4WD and 4H/4LO.

4WD warning lamp

• Illuminates if malfunction is detected in 4WD system.
• Flashes (1 flash / 2 seconds) if rotation difference of front wheels and rear wheels is large.

ATP warning lamp

Indicates that A/T parking mechanism does not operate when A/T selector lever is in “P” position be-
cause transfer case is in neutral.

4WD shift indicator lamp

Displays driving range selected by 4WD shift switch.

4LO indicator lamp

Displays 4LO range.

ABS actuator and electric unit
(control unit)

Transmits the following signals via CAN communication to transfer control unit.
• Vehicle speed signal
• Stop lamp switch signal (brake signal)

TCM

Transmits the following signal via CAN communication to transfer control unit.
• Output shaft revolution signal
• A/T position indicator signal (transmission range switch signal)

ECM

Transmits engine speed signal via CAN communication to transfer control unit.

4WD SYSTEM

System Description

INFOID:0000000005258361

TRANSFER CONTROL DEVICE

Integrates actuator motor and actuator position switch.

Actuator Motor

Moves shift rods when signaled by transfer control unit.

Actuator Position Switch

Detects actuator motor position and then sends signal to transfer control unit.

WAIT DETECTION SWITCH

Detects if transfer case is in 4WD by the 2-4 shift fork position.

NOTE:

If 4WD shift switch is switched to 4H or 4LO and the transfer case is not in 4WD completely, the wait detection

system will operate.

4LO SWITCH

4LO switch detects if the transfer case is in 4LO by the position of the L-H shift fork.

ATP SWITCH

ATP switch detects if transfer case is in neutral by the position of the L-H shift fork.

NOTE:

Transfer case may be in neutral when shifting between 4H-4LO.

TRANSFER CONTROL UNIT

• Transfer control unit controls transfer control device and it directs shifts from 4H-4LO and 2WD-4WD.

• Self-diagnosis can be done.

TRANSFER SHIFT HIGH AND LOW RELAYS

Transfer shift high and low relays apply power supply to transfer control device (actuator motor).

TRANSFER SHUT OFF RELAYS

Transfer shut off relays 1 and 2 apply power supply to transfer control unit.

4WD SHIFT SWITCH AND INDICATOR LAMP

4WD Shift Switch

4WD shift switch is able to select from 2WD, 4H or 4LO.

4WD Shift Indicator Lamp

• Displays driving conditions selected by the 4WD shift switch while engine is running. When the 4WD warn-

ing lamp is turned on, all 4WD shift indicator lamps will turn off.

• Turns ON when ignition switch is turned ON, for purpose of lamp check. Turns OFF approximately for 1 sec-

ond after the engine starts if system is normal.

4LO Indicator Lamp

• Displays 4LO while engine is running. 4LO indicator lamp flashes if transfer gear does not shift completely

into 4H

⇔

4LO. In this condition, the transfer case may be in neutral and the A/T parking mechanism may not

operate.

• Turns ON when ignition switch is turned ON, for purpose of lamp check. Turns OFF approximately for 1 sec-

ond after the engine starts if system is normal.

4WD WARNING LAMP

Turns on or flashes when there is a malfunction in 4WD system.

Also turns on when ignition switch is turned ON, for purpose of lamp check. Turns OFF approximately for 1

second after the engine starts if system is normal.

4WD Warning Lamp Indication

ATP WARNING LAMP

When the A/T selector lever is in “P” position, the vehicle may move if the transfer case is in neutral. ATP

warning lamp is turned on to indicate this condition to the driver.

Condition

4WD warning lamp

System normal

OFF

Lamp check

Turns ON when ignition switch is turned ON.

Turns OFF after engine start.

4WD system malfunction

During self-diagnosis

Flashes malfunction mode.

Large difference in diameter of front/
rear tires

Flashes slow (1 flash / 2 seconds)

(Continues to flash until the ignition switch is turned OFF)
