PCS-12 < SYSTEM DESCRIPTION > [IPDM E/R] SYSTEM POWER CONSUMPTION CONTROL SYSTEM : System Description INFOID:0000000010434018 SYSTEM DIAGRAM DESCRIPTION Outline • IPDM E/R incorporates a power consumption control function that reduces the power consumption accord- ing to the vehicle status. • IPDM E/R changes its status (control mode) with the sleep wake up signal received from BCM via CAN com- munication. Normal mode (wake-up) - CAN communication is normally performed with other control units. Low power consumption mode (sleep) - Low power consumption control is active. Sleep Mode Activation • IPDM E/R judges that the sleep-ready conditions are fulfilled when the ignition switch is OFF and none of the conditions below are present. Then it transmits a sleep-ready signal (ready) to BCM via CAN communica- - Outputting signals to actuators wake up signal (sleep) from BCM and the sleep-ready conditions are fulfilled. Wake-Up Operation • IPDM E/R changes from the low power consumption mode to the normal mode when it receives a sleep wake-up signal (wake up) from BCM or any of the following conditions is fulfilled. In addition, it transmits a - Ignition switch ON ENERGY MANAGEMENT SYSTEM JMMIA1759GB |
