4WD WARNING LAMP BLINKS QUICKLY

Description

INFOID:0000000000972117

While driving, 4WD warning lamp blinks 2 times in 1 second 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.

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

be restored.
