IPDM E/R changes its status (control mode) with the sleep wake up signal received from BCM via CAN communication. Normal mode (wake-up) - CAN communication is normally performed with other control units. - Individual unit control by IPDM E/R is normally performed. Low power consumption mode (sleep) - Low power consumption control is active. - CAN transmission is stopped. SLEEP MODE ACTIVATI IPDM E/R judges that the sleep-ready conditions are fulfilled when the ignition switch is and none of the conditions below are present. Then it transmits a sleep-ready signal (ready) to BCM via CAN communication. - Front wiper fail-safe operation - Outputting signals to actuators - Switches or relays operating - Auto active test is starting - Emergency - Output requests are being received from control units via CAN communication. IPDM E/R stops CAN communication and enters the low power consumption mode when it receives a sleep wake up signal (sleep) from BCM and the sleep-ready conditions are fulfilled. WAKE-UP OPERATI 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 sleep-ready signal (not-ready) to BCM via CAN communication to report the CAN communication start. - Ignition switch - An output request is received from a control unit via CAN communication.
