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

< ECU DIAGNOSIS >

[XENON TYPE]

IPDM E/R (INTELLIGENT POWER DISTRIBUTION MODULE ENGINE ROOM)

If No CAN Communication Is Available With BCM

IGNITION RELAY MALFUNCTION DETECTION FUNCTION

• IPDM E/R monitors the voltage at the contact circuit and excitation coil circuit of the ignition relay inside it. 
• IPDM E/R judges the ignition relay error if the voltage differs between the contact circuit and the excitation

coil circuit.

• 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 auto stop 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

• Turns ON the cooling fan relay-2 and the cooling fan relay-3 when ignition switch is 

turned ON (Cooling fan operates at HI)

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

when the ignition switch is turned OFF (Cooling fan does not operate)

A/C compressor

A/C relay OFF

Alternator

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

Control part

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
• License plate lamps
• Side  maker  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/AUTO mode and the 
front wiper motor is operating.
