IPDM E/R Status Control

In order to save power, IPDM E/R switches status by itself based on each operating condition.

1. CAN communication status
   • CAN communication is normally performed with other control units.
   • Individual unit control by IPDM E/R is normally performed.
   • When sleep request signal is received from BCM, mode is switched to sleep transient status.
2. Sleep transient status
   • Process to stop CAN communication is activated.
   • All systems controlled by IPDM E/R are stopped. When 3 seconds have elapsed after CAN communication with other control units is stopped, mode switches to sleep status.
3. Sleep status
   • IPDM E/R operates in low power mode.
   • CAN communication is stopped.
   • When a change in CAN communication line is detected, mode switches to CAN communication status.
   • When a change hood switch or ignition switch signal is detected, mode switches to CAN communication status.
