IPDM Status Control

In order to save power, IPDM 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 is normally performed.
   • When sleep request signal is received from BCM, mode is switched to sleep waiting status.
2. Sleep Waiting Status
   
   
   • Process to stop CAN communication is activated.
   • All systems controlled by IPDM 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 operates in low current-consumption mode.
   • CAN communication is stopped.
   • When a change in CAN communication line is detected, mode switches to CAN communication status.
