CONFIGURATION (BCM) : Description
Vehicle specification needs to be written with CONSULT-III because it is not written after replacing BCM. Configuration has three functions as follows
| Function | Description |
|---|---|
| READ CONFIGURATION | Reads the vehicle configuration of current BCM. Saves the read vehicle configuration. |
| WRITE CONFIGURATION - Manual setting | Writes the vehicle configuration with manual selection. |
| WRITE CONFIGURATION - Config file | Writes the vehicle configuration with saved data. |
BCM DESCRIPTION CHART
Note. Manual setting item: Items which need selection by vehicle specifications Automatic setting item: Items which are written in automatically (Setting cannot be changed)
| CAUTION | When replacing BCM, you must perform "WRITE CONFIGURATION" with CONSULT-III. Complete the procedure of "WRITE CONFIGURATION" in order. If you set incorrect "WRITE CONFIGURATION", incidents might occur. Configuration is different for each vehicle model. Confirm configuration of each vehicle model. Never perform "WRITE CONFIGURATION" except for new BCM. |
WIPER INTERMITTENT DIAL POSITION SETTING (FRONT WIPER INTERMITTENT OPERATION)
BCM judges the wiper intermittent dial 1 - 7 by the status of INT VOLUME 1, 2, and 3 switches.
| Wiper intermittent dial position | Intermittent operation delay interval | INT VOLUME switch ON/OFF status | ||
|---|---|---|---|---|
| INT VOLUME 1 switch | INT VOLUME 2 switch | INT VOLUME 3 switch | ||
| 1 | Short ↑ ↓ Long | ON | ON | ON |
| 2 | ON | ON | OFF | |
| 3 | ON | OFF | OFF | |
| 4 | OFF | OFF | OFF | |
| 5 | OFF | OFF | ON | |
| 6 | OFF | ON | ON | |
| 7 | OFF | ON | OFF | |

Wake-up operation
- BCM changes from the low power consumption mode to the CAN communication sleep mode when 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 combination meter transmits the wake up signal to BCM via CAN communication to report the CAN communication start.
Wake-up condition
| BCM wake-up condition | CAN wake-up condition |
|---|---|
| Door unlock sensor: OFF-->ON, ON-->OFF Door lock lock assembly LH (key cylinder switch): Lock or unlock Door lock switch: OFF-->ON Door unlock switch: OFF-->ON Trunk lid opener switch: OFF-->ON Power window serial link communication: Receiving Remote keyless entry receiver: Receiving valid keyfob | Receiving the sleep-ready signal (Not-ready) from any units Key slot: OFF-->ON, ON-->OFF Push-button ignition switch (push switch): OFF-->ON Hazard switch: OFF-->ON PASSING switch: OFF-->ON, ON-->OFF TAIL LAMP switch: OFF-->ON Driver door switch: OFF-->ON, ON-->OFF Passenger door switch: OFF --> ON, ON --> OFF Trunk room lamp switch: OFF-->ON, ON-->OFF Driver door request switch: OFF-->ON Passenger door request switch: OFF-->ON Trunk request switch: OFF-->ON Stop lamp switch 2 signal: ON Remote keyless entry receiver: Receiving valid keyfob |
