BCS SYSTEM BCS-13 < SYSTEM DESCRIPTION > [WITH INTELLIGENT KEY SYSTEM] C D E F G H I J K L B A O P N SIGNAL BUFFER SYSTEM : System Description INFOID:0000000009268610 OUTLINE BCM has the signal transmission function that outputs/transmits each input/received signal to each unit. Signal transmission function list POWER CONSUMPTION CONTROL SYSTEM INFOID:0000000009268611 POWER CONSUMPTION CONTROL SYSTEM : System Description INFOID:0000000009268612 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 Signal name Input Output Description • Ignition switch ON signal Engine switch (push switch) IPDM E/R (CAN) Inputs the push-button ignition Door switch signal Any door switch • Combination meter (CAN) Inputs the door switch signal ALCIA0030GB |
