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.

Description

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.

If No CAN Communication Is Available With ECM

Control part

Fail-safe operation

Cooling fan
  • The cooling fan relay-1 turn ON when the ignition switch is turned ON (Cooling fan HI operation)
  •  The cooling fan relay-1 turn OFF when the ignition switch is turned OFF
A/C compressor A/C relay OFF

Control part

Fail-safe operation

Front wiper motor
  • The status just before activation of fail-safe control is maintained until the ignition switch is turned OFF while the front wiper is operating at LO or HI speed.
  •  The wiper is operated at LO speed until the ignition switch is turned OFF if the fail-safe control is activated while the front wiper is set in the INT mode and the front wiper motor is operating.
  •  Returns automatically wiper to stop position when ignition switch is turned ON if fail-safe control is activated while front wiper motor is operated and wiper stop in the other position than stop position.

IGNITION RELAY MALFUNCTION DETECTION FUNCTION

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

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.
