System Description
SYSTEM DIAGRAM
DESCRIPTION
The IPDM E/R activates the internal control circuit to perform relay ON-OFF control according to the input signals from various sensors and the request signals received from control units via CAN communication.
NOTE:
IPDM E/R integrated relays cannot be removed.
