• BCM (Body Control Module) controls the various electrical components. It inputs the information required to
the control from CAN communication and the signal received from each switch and sensor.
• BCM has combination switch reading function for reading the operation status of combination switches (light,
turn signal, wiper and washer) in addition to a function fo r controlling the operation of various electrical com-
ponents. It also has the signal transmission function as the passed point of signal and the power saving con-
trol function that reduces the power c onsumption with the ignition switch OFF.
• BCM is equipped with the diagnosis function that performs the diagnosis with CONSULT and various set- tings.

Combination Switch Circuit (Without Variable Intermittent Wipers)
OUTLINE
• BCM reads the status of the combination switch (light, turn signal, wiper and washer) and recognizes the
status of each switch.
• BCM has a combination of 5 output terminals (OUTPUT 1 - 5) and 5 input terminals (INPUT 1 - 5). It reads a
maximum of 20 switch states.
