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
1.CHECK DOOR KEY CYLINDER SWITCH INPUT SIGNAL
Check KEY CYL UN-SW, KEY CYL UN-SW in “DATA MO NITOR” mode for “POWER DOOR LOCK SYSTEM”
with CONSULT. Refer to DLK-81, "Work Flow"
.
Is the inspection result normal?
YES >> Key cylinder switch is OK.
NO >> With LH and RH anti-pinch, refer to DLK-115, "Diagnosis Procedure (With LH and RH Anti-
Pinch)".
NO >> With LH anti-pinch only, refer to DLK-116, "Diagnosis Procedure (With LH Anti-Pinch Only)"
.
