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 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 PROTECTION FUNCTION

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.

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.

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 lamp
• License plate lamp
• Illumination
• Tail  lamp

• 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 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.
