COMBINATION SWITCH READING FUNCTION
Description
NOTE: BCM reads the status of the combination switch at 60 ms intervals when BCM is controlled at low power consumption control mode.
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
Example 2: When some switches (TAIL LAMP, TURN RH) are turned ON
WIPER INTERMITTENT DIAL POSITION SETTING (FRONT WIPER INTERMITTENT OPERATION)
BCM judges the wiper intermittent dial 1 - 4 by the status of INT VOLUME 1, 2, and 3 switches.
