4WD HIGH TEMP IS DISPLAYED ON INFORMATION DISPLAY

Description

INFOID:0000000009177763

While driving, 4WD warning indicator is quickly blinked on information display and it turns OFF after 1 minute.

• This symptom protects drivetrain parts when a heavy load is applied to the electric controlled coupling and

multiple disc clutch temperature increases. Also, optional distribution of torque sometimes becomes rigid

before lamp blinks quickly. Both cases are not malfunction. Refer to 

DLN-22, "Protection Function"

.

• When this symptom occurs, stop vehicle and allow it to idle for some times. Blinking will stop and system will

be restored.
