• The circuit between OUTPUT 4 and INPUT 5 is formed when the TAIL LAMP switch is turned ON.
• BCM detects the combination switch status signal “5D” when the signal of OUTPUT 4 is input to INPUT 5.
• BCM judges that the TAIL LAMP switch is ON when the signal “5D” is detected.
Example 2: When some switches (TURN RH switch, TAIL LAMP switch) are turned ON
• The circuits between OUTPUT 1 and INPUT 5 and between OUTPUT 4 and INPUT 5 are formed when the
TURN RH switch and TAIL LAMP switch are turned ON.
• BCM detects the combination switch status signal “5AD” when the signals of OUTPUT 1 and OUTPUT 4 are
input to INPUT 5.
• BCM judges that the TURN RH switch and TAIL LAMP switch are ON when the signal “5AD” is detected.
WIPER INTERMITTENT DIAL POSITION
BCM judges the wiper intermittent dial 1 - 7 by the status of INT VOLUME 1, 2 and 3 switches.

Description
Ignition switch ON signal
Push-button ignition switch
(Push switch)
IPDM E/R (CAN)
Inputs the push-button ignition
switch (push switch) signal and
transmits the ignition switch sta-
tus judged with BCM via CAN
communication.
Door switch signal
Any door switch
• Combination meter (CAN)
• IPDM E/R (CAN)
Inputs the door switch signal
and transmits it via CAN com-
munication.
Blower fan ON signal
A/C auto amp.
ECM (CAN)
Input blower fan switch signal,
and transmit the blower fan ON
signal via CAN communication.
A/C ON signal
A/C auto amp.
ECM (CAN)
Input A/C ON signal and trans-
mit the A/C ON signal via CAN
communication.
Oil pressure switch signal
IPDM E/R (CAN)
Combination meter (CAN)
Transmits the received oil pres-
sure switch signal via CAN
communication.
