Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT PRE-TENSIONER"

The Supplemental Restraint System such as "AIR BAG" and "SEAT BELT PRE- TENSIONER", used along with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain types of collision. Information necessary to service the system safely is included in the " SRS AIRBAG " and " SEAT BELTS SRS AIRBAG " articles of this Service Information.

Scheme 52

Scheme 53

OUTLINE

1. BCM (Body Control Module) controls the various electrical components. It inputs the information required to the control from CAN communication and the signal received from each switch and sensor.
2. BCM has combination switch reading function for reading the operation status of combination switches (light, turn signal, wiper and washer) in addition to a function for controlling the operation of various electrical components. It also has the signal transmission function as the passed point of signal and the power saving control function that reduces the power consumption with the ignition switch OFF.
3. BCM is equipped with the diagnosis function that performs the diagnosis with CONSULT and various settings.

BCM CONTROL FUNCTION LIST

Scheme 54

1. BCM reads the status of the combination switch (light, turn signal, wiper and washer) and recognizes the status of each switch.
2. BCM has a combination of 5 output terminals (OUTPUT 1 - 5) and 5 input terminals (INPUT 1 - 5). It reads a maximum of 20 switch states.

COMBINATION SWITCH INPUT-OUTPUT SYSTEM LIST

COMBINATION SWITCH READING FUNCTION

Description

Scheme 56

Scheme 57

1. 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.
2. 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 (TAIL LAMP) is turned ON

Scheme 58

1. The circuit between OUTPUT 4 and INPUT 5 is formed when the TAIL LAMP switch is turned ON.
2. BCM detects the combination switch status signal "5D" when the signal of OUTPUT 4 is input to INPUT 5.
3. BCM judges that the TAIL LAMP switch is ON when the signal "5D" is detected.

Example 2: When some switches (TURN RH, TAIL LAMP) are turned ON

Scheme 59

1. The circuits between OUTPUT 1 and INPUT 5 and between OUTPUT 4 and INPUT 5 are formed when the TURN RH switch and TAIL LAMP switch are turned ON.
2. BCM detects the combination switch status signal "5AD" when the signals of OUTPUT 1 and OUTPUT 4 are input to INPUT 5.
3. BCM judges that the TURN RH switch and TAIL LAMP switch are ON when the signal "5AD" is detected.

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 " FRONT WIPER AND WASHER SYSTEM: SYSTEM DESCRIPTION ".

Scheme 60

BCM has the signal transmission function that outputs/transmits each input/received signal to each unit.

SIGNAL TRANSMISSION FUNCTION LIST

Scheme 61

1. BCM incorporates a power saving control function that reduces the power consumption according to the vehicle status.
2. 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)

1. CAN communication is normally performed with other units
2. Each control with BCM is operating properly

CAN communication sleep mode (CAN sleep)

1. CAN transmission is stopped
2. Control with BCM only is operating

Low power consumption mode (BCM sleep)

1. Low power consumption control is active
2. 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.

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

Sleep mode activation

1. BCM receives the sleep-ready signal (ready) from IPDM E/R and combination meter via CAN communication.
2. BCM transmits the sleep wake up signal (sleep) to each unit when all of the CAN sleep conditions are fulfilled.
3. Each unit stops the transmission of CAN communication with the sleep wakeup signal. BCM is in CAN communication sleep mode.
4. 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 DESCRIPTION

Wake-up operation

1. 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.
2. 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.
3. Each unit starts the transmission of CAN communication with the sleep wake up signal. In addition, the combination meter transmits the wake up signal to BCM via CAN communication to report the CAN communication start.
