Nissan Juke Service and Repair Manual : 4WD warning lamp blinks quickly

• 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-32,

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