Relay control system
Relay control system : system diagram
Relay control system : system description
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.
Caution:
Ipdm e/r integrated relays cannot be removed.
Power consumption control system

Description
Outline
Normal mode (wake-up)
Low power consumption mode (sleep)
Sleep mode activation
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.
Diagnosis system (ipdm e/r)
Diagnosis description
Auto active test
Description
In auto active test, the ipdm e/r sends a drive signal to the following systems to check their operation.
Operation procedure
Note:
Never perform auto active test in the following conditions.
Note:
When auto active test is performed with hood opened, sprinkle water on windshield beforehand.
Note:
Inspection in auto active test
When auto active test is actuated, the following operation sequence is repeated 3 times.
Concept of auto active test
Therefore, the can communication line between ipdm e/r and bcm is considered normal if the auto active test starts successfully.
