LIN child lock signal:
The window lifter motor can get child lock switch status from the signal sent by BCM. When
lifter motor doesn’t receive child lock switch status, the motor will deem child lock not closed.
The child lock switch can interrupt the input of local window lifter switch on the passenger side.
When the child lock is activated, the passenger side window lifter motor will not receive input
signal corresponding to the local switch.
If the driver side is the left side, FR door and rear doors are on passenger side;
If the driver side is the right side, FL door and rear doors are on passenger side;
When the passenger side glass is working, activate the child lock, and the glass will
immediately stop.
Description of fault protection function (with anti-pinch function):
The window lifter motor is controlled by the relay in the motor anti-pinch module:
When the anti-pinch module detects upper or lower limit position of the glass, the anti-pinch
module will stop driving the lifter motor (the stalling time is 400ms
±
50ms).
20s after the receipt of glass lifting signal, if the glass is not raised or lowered to its limit
position, the motor will stop working.
The anti-pinch force is less than 100N. As for the specific control strategy, refer to instructions
on anti-pinch function.
