RELAY CONTROL SYSTEM
RELAY CONTROL SYSTEM : System Description
SYSTEM DIAGRAM
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.
RELAY CONTROL SYSTEM : Fail-safe
CAN COMMUNICATION CONTROL
When CAN communication with ECM and BCM is impossible, IPDM E/R performs fail-safe control. After CAN communication recovers normally, it also returns to normal control.

IGNITION RELAY MALFUNCTION DETECTION FUNCTION
FRONT WIPER CONTROL
IPDM E/R detects front wiper stop position by a front wiper auto stop signal.
When a front wiper auto stop signal is in the conditions listed below, IPDM E/R stops power supply to wiper after repeating a front wiper 10 second activation and 20 second stop five times.
NOTE: This operation status can be confirmed on the IPDM E/R “Data Monitor” that displays “BLOCK” for the item “WIP PROT” while the wiper is stopped.
STARTER MOTOR PROTECTION FUNCTION
IPDM E/R turns OFF the starter relay to protect the starter motor when the starter relay remains active for 90 seconds.
SMART FIELD-EFFECT TRANSISTOR (FET)
SMART FIELD-EFFECT TRANSISTOR (FET) : System Description
A smart Field-Effect Transistor (FET) is a transistor used to monitor and control current flow on module outputs.
The IPDM E/R uses a smart FET protection strategy to prevent module damage in the event of excessive current flow. The smart FET protection strategy monitors its outputs for excessive current, and when a fault occurs, shuts down the output and records a DTC.
