COMBINATION SWITCH READING FUNCTION
Description
• BCM reads the status of the combination switch at 10 ms intervals normally.
NOTE:
BCM reads the status of the combination switch at 60 ms intervals when BCM is controlled at low power
consumption control mode.
• BCM operates as follows and judges the status of the combination switch.
- It operates the transistor on OUTPUT side in the following order: OUTPUT 1
→ 2 → 3 → 4 → 5, and outputs
voltage waveform.
- The voltage waveform of OUTPUT corresponding to the formed circuit is input into the interface on INPUT
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 the 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 (TAIL LAMP) is turned ON
• The circuit between OUTPUT 4 and INPUT 5 is formed when the TAIL LAMP switch is turned ON.

Combination switch circuit (With Variable Intermittent Wipers)
Combination switch circuit (Without Variable Intermittent Wipers)
• 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, TAIL LAMP) 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.

Combination switch circuit (Without Variable Intermittent Wipers)
• 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 (WITH VARIABLE INTERMITTENT WIPERS)
BCM judges the wiper intermittent dial 1 - 7 by the status of INT VOLUME 1, 2 and 3 switches.
NOTE:
For details of wiper intermittent dial position, refer to
