KEY CYLINDER SWITCH
DescriptionINFOID:0000000009461844
For vehicles equipped with LH and RH anti-pinch system, the main power window and door lock/unlock switch
detects condition of the door key cylinder switch and transmits to BCM as the LOCK or UNLOCK signal.
For vehicles equipped with LH anti-pinch system only, t he front door lock assembly LH (key cylinder switch)
transmits the LOCK or UNLOCK signal directly to the BCM.
Component Function CheckINFOID:0000000009461845
