Combination Switch Reading Function - 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 (TURN RH) is turned ON

• The circuit between OUTPUT 3 and INPUT 5 is formed when the TURN RH switch is turned ON.

• BCM detects the combination switch status signal "5C" when the signal of OUTPUT 3 is input to INPUT 5.
• BCM judges that the TURN RH switch is ON when the signal "5C" is detected.

Example 2: When some switches (FR FOG, TURN RH) are turned ON

• The circuits between OUTPUT 1 and INPUT 5 and between OUTPUT 3 and INPUT 5 are formed when the FR FOG switch and TURN RH switch are turned ON.

• BCM detects the combination switch status signal "5AC" when the signals of OUTPUT 1 and OUTPUT 3 are input to INPUT 5.
• BCM judges that the FR FOG switch and TURN RH switch are ON when the signal "5AC" is detected.
