Combination Switch Reading Function - Operation Example

WARNING: This page is about a different car, the 2016 Nissan Rogue. 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) 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 (TAIL LAMP, TURN RH) are turned ON

The circuits between OUTPUT 2 and INPUT 5 and between OUTPUT 3 and INPUT 5 are formed when the TAIL LAMP switch and TURN RH switch are turned ON.

BCM detects the combination switch status signal "5BC" when the signals of OUTPUT 2 and OUTPUT 3 are input to INPUT 5.
BCM judges that the TAIL LAMP switch and TURN RH switch are ON when the signal "5BC" is detected.
