POWER WINDOW SERIAL LINK

Description

INFOID:0000000003573501

Power window main switch, front power window switch (passenger side), and BCM transmit and receive the
signal by power window serial link.
The signal mentioned below is transmitted from BCM to power window main switch, front power window (pas-
senger side).
•  Keyless power window down signal
The signal mentioned below is transmitted from power window main switch to front power window switch (pas-
senger side).
• Passenger side door window operation signal
• Power window control by key cylinder switch signal
• Power window lock switch signal
• Retained power operation signal 

Component Function Check

INFOID:0000000003573502
