RELAY CONTROL SYSTEM
System Description
INFOID:0000000001697580
IPDM E/R activates the internal control circuit to perform the relay ON-OFF control according to the input sig-
nals from various sensors and the request signals received from control units via CAN communication.
CAUTION:
IPDM E/R integrated relays cannot be removed.

CONSULT - III Function (IPDM E/R)INFOID:0000000001697590
APPLICATION ITEM
CONSULT-III performs the following functions via CAN communication with IPDM E/R.
SELF DIAGNOSTIC
Refer to PCS-28, "DTCIndex".
DATA MONITOR
Monitor item
Diagnosis mode Description
ECU Identification Allows confirmation of IPDM E/R part number.
Self Diagnostic Result Displays the diagnosis results judged by IPDM E/R.
Data Monitor Displays the real-time input/output data from IPDM E/R input/output data.
Active Test IPDM E/R can provide a drive signal to electronic components to check their operations.
CAN Diag Support Monitor The results of transmit/receive diagnosis of CAN communication can be read.
