5. Window & anti-pinch sunroof system

Description of fault protection function
The window lifter motor is controlled by relay in BCM:
When BCM detects upper/lower limit position of the glass, BCM will stop driving window lifter motor
(the stalling time is 400ms±50ms).
After 8s of BCM receives glass lifting signal, if the glass is not raised or lowered to its limit position,
the lifter motor will stop working.
Where a certain external resistance is detected, BCM will stop the relay working to protect the circuit
and avoid any pinch.
