OPTICAL SENSOR
The PTG drive unit uses an optical sensor that is located on the drive unit clutch housing and sends motor speed signals to the ECU. This speed signal is used by the PTGM to control the motor and to detect obstacles in the Power Tailgate path.
The optical sensor cannot be adjusted or repaired, and if found to be faulty, must be replaced.

OPTICAL SENSOR INSPECTION
1. Check the power tailgate control module input/output value by using the diagnostic tool If the operation of tailgate control module is abnormal, replace power tailgate drive unit.
