Transfer: Motor-Shift Type (Transfer with Shift Actuator) 3C-5
Function of 4WD Control System Component
S5JB0A3311003
4WD Control System Operation
S5JB0A3311005
Instead of the transfer shift lever assembly, the transfer position (4H, 4H-lock, N and 4L-lock) is shifted automatically
by operating the transfer switch.
The 4WD control module operates the transfer shift actuator according to the transfer switch operation.
4H (4WD High) Position
The driving force from the transmission is transmitted to the transfer input gear. As the center LSD case and transfer
input gear are engaged via the reduction shift sleeve at this time, the driving force transmitted from the transfer input
gear to the rear output shaft rotates them at the same speed.
Also, driving force from the center LSD is transmitted to the front drive shaft through front drive sprocket. Then, the
front drive sprocket rotates the front output shaft via the drive chain.
Part Name Function
4L/N switch
Detects transfer shift position combining center differential lock
switch.
Center differential lock switch Detects transfer shift position combining 4L/N switch.
Transfer switch Shifts transfer shift position.
N indicator Indicates transfer is at N position or not.
4L indicator Indicates transfer is at 4L-lock position or not.
Differential lock indicator Indicates transfer is at 4H-lock, 4L-lock or not.
Transmission range sensor (N position) (for A/T
model)
Detects A/T is at N range or not.
CPP switch Detects clutch pedal is depressed or not.
Buzzer incorporated into BCM
• Indicates transfer is at “N” position.
• Warns of prohibited shift operation.
4WD control module
• Controls transfer shifting.
• Diagnoses 4WD control system components.
• Output operation signal of indicators and buzzer to BCM.
Transfer shift actuator
• Consists of transfer shift actuator motor and transfer shift
actuator motor position switch.
• Shifts transfer shift position operating High / Low shift fork and
differential lock shift fork via cams.
• Detects transfer shift actuator motor position.
Diagnosis connector
Indicates DTC on indicators when grounding its diagnosis
terminal.
