BCS POWER CONSUMPTION CONTROL SYSTEM BCS-101 < SYSTEM DESCRIPTION > [WITHOUT INTELLIGENT KEY SYSTEM] C D E F G H I J K L B A O P N POWER CONSUMPTION CONTROL SYSTEM System Diagram INFOID:0000000009949762 System Description INFOID:0000000009949763 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 CAN communication sleep mode (CAN sleep) - CAN transmission is stopped Low power consumption mode (BCM sleep) - Low power consumption control is active LOW POWER CONSUMPTION CONTROL WITH BCM BCM reduces the power consumption with the following operation in the low power consumption mode. 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 JPMIA0731GB CAN sleep condition BCM sleep condition • Receiving the sleep-ready signal (ready) from all units • Interior room lamp battery saver: Time out tion • Remote keyless entry receiver communication status: No com- munication • Tire pressure monitor system (TPMS) - AIR PRESSURE MON- ITOR: Stop |
