Operation Example

WARNING: This page is about a different car, the 2011 Suzuki Equator. However, it is still accessible from the selected car via links, so may be relevant.

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 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 "1E" 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 switch, front wiper LO switch) are turned ON
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 WIPER LOW switch are ON when the signal "1CE" is detected.
