CONFIGURATION (BCM): Description
Vehicle specification needs to be written with CONSULT 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 selection | Writes the vehicle configuration with manual selection. |
| WRITE CONFIGURATION - Config file | Writes the vehicle configuration with saved data. |
Note. Manual setting item: Items which need selection by vehicle specifications Automatic setting item: Items which are written in automatically (Setting can not be changed) For some models and specifications, the automatic setting item may not be displayed.
| CAUTION | When replacing BCM, always perform "WRITE CONFIGURATION" with CONSULT. Or not doing so, BCM control function does not operate normally. Complete the procedure of "WRITE CONFIGURATION" in order. Configuration is different for each vehicle model. Confirm configuration of each vehicle model. Never perform "WRITE CONFIGURATION" except for new BCM. If you set incorrect "WRITE CONFIGURATION", incidents might occur. |
DESCRIPTION
- The combination meter transmits meter CAN signal*1 to BCM via CAN communication, when the extended storage fuse switch is ON.
- BCM switches the status (shipping mode or normal mode) by itself according to the meter CAN signal*1 from combination meter, and transmits shipping mode status signal to combination meter via CAN communication.
- The combination meter displays extended storage fuse warning message*2 on the information display, and turns the turn signal indicator lamp (LH/RH) ON, when BCM is in shipping mode.
- BCM control functions are limited in shipping mode. Refer to " «DESCRIPTION»(ref-672646-S20376821022014112400000) ".
*1: Odometer signal, wake up signal and each signal.
*2: When shipping mode function operates, "SHIPPING MODE ON PUSH STORAGE FUSE" is displayed.
CAN (Controller Area Network) is a serial communication line for real time applications. It is an on-vehicle multiplex communication line with high data communication speed and excellent error detection ability. Modern vehicle is equipped with many electronic control unit, and each control unit shares information and links with other control units during operation (not independent). In CAN communication, control units are connected with 2 communication lines (CAN H-line, CAN L-line) allowing a high rate of information transmission with less wiring. Each control unit transmits/receives data but selectively reads required data only.
CAN Communication Signal Chart. Refer to " CAN COMMUNICATION SYSTEM: CAN COMMUNICATION SIGNAL CHART ".
U0415 is displayed if any unusual condition is present in the reception status of the vehicle speed signal from the ABS actuator and electric unit (control unit).
