If No CAN Communication Is Available With BCM

IGNITION RELAY MALFUNCTION DETECTION FUNCTION

• IPDM E/R monitors the voltage at the contact circuit of the ignition relay inside and ignition switch status

from BCM via CAN communication.

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

switch status from BCM via CAN communication.

• If the ignition relay cannot turn OFF due to contact seizure, it activates the tail lamp relay for 10 minutes to

alert the user to the ignition relay malfunction when the ignition switch is turned OFF.

FRONT WIPER CONTROL

IPDM E/R detects front wiper stop position by a front wiper stop position signal.
When a front wiper stop position signal is in the conditions listed below, IPDM E/R stops power supply to wiper
after repeating a front wiper 10 seconds activation and 20 seconds stop five times.

Control part

Fail-safe operation

Cooling fan

• The cooling fan relay-1, the cooling fan relay-2 and the cooling fan relay-3 turn ON

when the ignition switch is turned ON (Cooling fan HI operation)

• The cooling fan relay-1, the cooling fan relay-2 and the cooling fan relay-3 turn OFF

when the ignition switch is turned OFF

A/C compressor

A/C relay OFF

Alternator

Outputs the power generation command signal (PWM signal) 0%

Control part

Fail-safe operation

Headlamp

• Turns ON the headlamp low relay when the ignition switch is turned ON
• Turns OFF the headlamp low relay when the ignition switch is turned OFF
• Headlamp high relay OFF

• Parking lamps
• Side marker lamps
• License plate lamps
• Illuminations
• Tail lamps

• Turns ON the tail lamp relay when the ignition switch is turned ON
• Turns OFF the tail lamp relay when the ignition switch is turned OFF

Front wiper

• 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.
