System Description
IPDM E/R activates the internal control circuit to perform the relay ON-OFF control according to the input signals from various sensors and the request signals received from control units via CAN communication.

Scheme 73
IPDM E/R reads the status of the oil pressure switch and transmits the oil pressure switch signal to BCM via CAN communication. Refer to " SYSTEM DESCRIPTION ".
Scheme 74
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 sleep-ready signal (not-ready) to BCM via CAN communication to report the CAN communication start. Ignition switch ON An output request is received from a control unit via CAN communication.
Scheme 75
Description
Refer to " SYSTEM DESCRIPTION ".
- PDS (POWER DISTRIBUTION SYSTEM) is the system that BCM controls with the operation of the ignition switch and performs the power distribution to each power circuit.
- If equipped with Intelligent Key, the ignition switch can be operated when Intelligent Key is in the detection area of the interior antenna.
- The ignition switch operation is input to BCM as a signal. BCM changes the power supply position according to the status and operates the ignition relay (inside IPDM E/R) to supply power to each power circuit.
