COMBINATION SWITCH READING FUNCTION
Description
• BCM reads the status of the combination switch at 10 ms interval normally.
NOTE:
BCM reads the status of the combination switch at 20 ms interval when BCM is controlled at low power con-
sumption control mode.
• BCM operates as follows and judges the status of the combination switch.
- INPUT 1 - 5 outputs the voltage waveforms of 5 systems simultaneously.
- It operates the transistor on OUTPUT side in the following order: OUTPUT 5 → 4 → 3 → 2 → 1.
System OUTPUT 1 OUTPUT 2 OUTPUT 3 OUTPUT 4 OUTPUT 5
INPUT 1 —FR WASHER FR WIPER LOW TURN LH TURN RH
INPUT 2 FR WIPER HI —FR WIPER INT PASSING HEADLAMP 1
INPUT 3 INT VOLUME 1 RR WASHER —HEADLAMP 2 HI BEAM
INPUT 4 RR WIPER INT INT VOLUME 3 AUTO LIGHT —TAIL LAMP
INPUT 5 INT VOLUME 2 RR WIPER —FR FOG —

- The voltage waveform of INPUT corresponding to the
formed circuit changes according to the operation of
the transistor on OUTPUT side if any (1 or more) switches are ON.
- It reads this change of the voltage as the status signal of the combination switch.
Operation Example
In the following operation example, the combination of t he status signals of the combination switch is replaced
as follows: INPUT 1 - 5 to “1 - 5” and OUTPUT 1 - 5 to “A - E”.
Example 1: When a switch (TURN RH switch) is turned ON
• The circuit between INPUT 1 and OUTPUT 5 is formed when the TURN RH switch is turned ON.
• BCM detects the combination switch status signal “1 E” when the signal of OUTPUT 5 is input to INPUT 1.
• BCM judges that the TURN RH switch is ON when the signal “1E” is detected.
Example 2: When some switches (turn RH s witch, front wiper LO switch) are turned ON

COMBINATION SWITCH READING SYSTEM
• The circuits between INPUT 1 and OUTPUT 5 and between INPUT 1 and OUTPUT 3 are formed when the
TURN RH switch and FR WIPER LOW switch are turned ON.
• BCM detects the combination switch status signal “1CE” when the signals of OUTPUT 3 and OUTPUT 5 are input to INPUT 1.
• BCM judges that the TURN RH switch and FR WIPE R LOW switch are ON when the signal “1CE” is
detected.

1. CHECK LIGHT & TURN SIGNAL SWITCH
Check operation with normal light and turn signal switch installed.
Does it operate normally?
YES >> Replace light and turn signal switch. Refer to EXL-154, "Removal and Installation".
NO >> GO TO 2
2. CHECK WIPER & WASHER SWITCH
Check operation with normal wiper and washer switch installed.
Does it operate normally?
YES >> Replace wiper and washer switch. Refer to WW-85, "Wiper and Washer Switch".
