  • Transmits the headlamp warning signal (CAN communication) to the combination meter (when the ignition switch is placed ON, the headlamp warning is displayed on the information display of the combination meter).

  • Transmits the request signal (via LIN communication) to the both side LED headlamp control module, and turns ON the headlamp (LO) and parking lamp.

  • Side marker lamp

  • Tail lamp
B20E2-96 LED HEADLAMP RH [CMPNENT INTERNAL MLFNCTN]

  • Transmits the headlamp warning signal (CAN communication) to the combination meter (when the ignition switch is placed ON, the headlamp warning is displayed on the information display of the combination meter).

  • Transmits the request signal (via LIN communication) to the both side LED headlamp control module, and turns ON the headlamp (LO) and parking lamp.

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 is operated at HI operation when the ignition switch is placed ON.

  • The cooling fan turns OFF when the ignition switch is placed OFF.
A/C compressor (magnetic clutch) A/C compressor (magnetic clutch) OFF

If No CAN Communication Is Available With BCM

Control part Fail-safe operation
Headlamp

  • Turns ON the headlamp (LO) when the ignition switch is placed ON.

  • Turns OFF the headlamp (LO) when the ignition switch is placed OFF.

  • Headlamp (HI): OFF

  • Parking lamp

  • License plate lamp

  • Side marker lamp

  • Tail lamp

  • Illumination

  • Turns ON the parking lamp, license plate lamp, side marker lamp, tail lamp and each illumination when the ignition switch is placed ON.

  • Turns OFF the parking lamp, license plate lamp, side marker lamp, tail lamp and each illumination when the ignition switch is placed OFF.
Front wiper

  • The status just before activation of fail-safe control is maintained until the ignition switch is placed OFF while the front wiper is operating at LO or HI speed.

  • The wiper is operated at LO speed until the ignition switch is placed 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.
Daytime running light Daytime running light: OFF
Ignition relay The status just before activation of fail-safe is maintained.
Starter motor Starter relay: OFF

IGNITION RELAY CONTROL

  • IPDM E/R monitors the voltage at the contact circuit of the ignition relay inside it.

  • IPDM E/R judges the ignition relay error if the voltage differs between the contact circuit.

Voltage judgement IPDM E/R judgement Operation
Ignition relay contact side Ignition relay control condition
ON ON Ignition relay ON normal —
OFF OFF Ignition relay OFF normal —
ON OFF Ignition relay ON stuck Detects DTC [B20DD-73: IGN RELAY ON CIRC]
OFF ON Ignition relay OFF stuck Detects DTC [B20DE-72: IGN RELAY OFF CIRC]

FRONT WIPER CONTROL

IPDM E/R detects front wiper stop position by front wiper stop position signal.

When front wiper stop position signal is in the condition listed below while the front wiper is operating, IPDM E/R activates the fail-safe.

Ignition switch Front wiper switch Front wiper stop position signal Fail-safe
ON OFF The signal does not change from the battery voltage for 10 seconds. Stops front wiper power supply for 20 seconds
Except OFF The signal does not change for 10 seconds.
