COMBINATION SWITCH READING FUNCTION

Description

• BCM reads the status of the combination switch at 10 ms intervals normally.

NOTE:

BCM reads the status of the combination switch at 60 ms intervals when BCM is controlled at low power

consumption control mode.

• BCM operates as follows and judges the status of the combination switch.

- 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 (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.

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.

SYSTEM DIAGRAM

OUTLINE

• BCM incorporates a power saving control function that reduces the power consumption according to the

vehicle status. 

• BCM switches the status (control mode) by itself with the power saving control function. It performs the sleep

request to each unit (IPDM E/R and combination meter) that operates with the ignition switch OFF.

Normal mode (wake-up)

- CAN communication is normally performed with other units

- Each control with BCM is operating properly

CAN communication sleep mode (CAN sleep)

- CAN transmission is stopped

- Control with BCM only is operating

Low power consumption mode (BCM sleep)

- Low power consumption control is active

- CAN transmission is stopped

LOW POWER CONSUMPTION CONTROL WITH BCM

BCM reduces the power consumption with the following operation in the low power consumption mode.

• The reading interval of each switch changes from 10 ms interval to 60 ms interval.

SLEEP MODE ACTIVATION

• BCM receives the sleep-ready signal (ready) from IPDM E/R and combination meter via CAN communica-

tion.

• BCM transmits the sleep wake up signal (sleep) to each unit when all of the CAN sleep conditions are ful-

filled.

• Each unit stops the transmission of CAN communication with the sleep wake-up signal. BCM is in CAN com-

munication sleep mode.

• BCM is in the low power consumption mode and performs the low power consumption control when all of the

BCM sleep conditions are fulfilled with CAN sleep condition.

Sleep condition

WAKE-UP OPERATION

• BCM changes from the low power consumption mode to the CAN communication sleep mode when the any

of the BCM wake-up conditions are fulfilled. Only the control with BCM is activated.

• BCM transmits the sleep wake-up signal (wake up) to each unit when any of the CAN wake-up conditions

are fulfilled. It changes from the low power consumption mode or the CAN communication sleep mode to the

normal mode.

• Each unit starts the transmission of CAN communication with the sleep wake-up signal. In addition, the com-

bination meter transmits the wake-up signal to BCM via CAN communication to report the CAN communica-

tion start.
