CAN COMMUNICATION CONTROL

When CAN communication with the ECM and BCM is impossible, the 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 (low) when the ignition switch is placed ON. Turns OFF the headlamp (low) when the ignition switch is placed OFF. Headlamp (high): OFF
Parking lamp License plate lamp Front 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-1	The status just before activation of fail-safe is maintained.
Starter motor	Starter relay: OFF

IGNITION RELAY CONTROL

The IPDM E/R monitors the voltage at the contact circuit of the ignition relay-1 inside it.
The IPDM E/R judges the ignition relay-1 error if the voltage differs between the contact circuit.

Voltage judgement		IPDM E/R judgement	Operation
Ignition relay-1 contact side	Ignition relay-1 control condition	IPDM E/R judgement	Operation
ON	ON	Ignition relay-1 ON normal	—
OFF	OFF	Ignition relay-1 OFF normal	—
ON	OFF	Ignition relay-1 ON stuck	Detects DTC [B20DD-73: IGN RELAY ON CIRC]
OFF	ON	Ignition relay-1 OFF stuck	Detects DTC [B20DE-72: IGN RELAY OFF CIRC]

FRONT WIPER CONTROL

The IPDM E/R detects the front wiper stop position from the front wiper stop position signal.

When the front wiper stop position signal is in the condition listed below while the front wiper is operating, the 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 battery voltage for 10 seconds.	Stops front wiper power supply for 20 seconds
ON	Except OFF	The signal does not change for 10 seconds.	Stops front wiper power supply for 20 seconds
