COMBINATION SWITCH READING SYSTEM

System Diagram

INFOID:0000000003441352

System Description

INFOID:0000000003441353

OUTLINE

• BCM reads the status of the combination switch (light, turn signal, wiper and washer) and recognizes the

status of each switch.

• BCM is a combination of 5 output terminals (OUTPUT 1 - 5) and 5 input terminals (INPUT 1 - 5). It reads a

maximum of 20 switch status.

COMBINATION SWITCH READING SYSTEM

NOTE:

Headlamp has a dual system switch.

COMBINATION SWITCH READING FUNCTION

Description

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

NOTE:
BCM reads the status of the combination switch at 60 ms interval when BCM is controlled at low power con-
sumption mode.

• BCM operates as follows and judges the status of the combination switch.
- INPUT 1 - 5 outputs the voltage waveforms of 5 systems simultaneously.
- It operates the transistor on OUTPUT side in the following order: OUTPUT 5

→

- The voltage waveform of INPUT corresponding to the formed circuit changes according to the operation of

the transistor on OUTPUT 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”.

< FUNCTION DIAGNOSIS >

• 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.

POWER CONSUMPTION CONTROL SYSTEM

System Diagram

INFOID:0000000003441357

System Description

INFOID:0000000003441358

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, combination meter, driver seat control unit and automatic back door control
unit) 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 the each switches 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 perform 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 is 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 is

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.
