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.
- 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
Example 2: When some switches (TURN RH, TAIL LAMP) are turned ON
TURN RH switch and TAIL LAMP switch are turned ON.
WIPER INTERMITTENT DIAL POSITION
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 WW "System Description".
