COOLING FAN CONTROL

IPDM E/R outputs pulse duty signal (PWM signal) to the cooling fan control module according to the status of

the cooling fan speed request signal received from ECM via CAN communication. Refer to 

EC-64, "COOLING

FAN CONTROL : System Diagram"

.

CAUTION:

After ignition switch OFF, IPDM E/R turn the cooling fan relay ON and outputs pulse duty signal (PWM

signal) to the cooling fan control module according to the request signal from ECM for cooling the

engine according to the situation.

ALTERNATOR CONTROL

IPDM E/R outputs power generation command signal (PWM signal) to the alternator according to the status of

the power generation command value signal received from ECM via CAN communication. Refer to 

CHG-8,

"POWER GENERATION VOLTAGE VARIABLE CONTROL SYSTEM : System Diagram"

POWER CONSUMPTION CONTROL SYSTEM : System Description

INFOID:0000000012197157

OUTLINE

• IPDM E/R incorporates a power consumption control function that reduces the power consumption accord-

ing to the vehicle status. 

• IPDM E/R changes its status (control mode) with the sleep wake up signal received from BCM via CAN com-

munication.

Normal mode (wake-up)

- CAN communication is normally performed with other control units.

- Individual unit control by IPDM E/R is normally performed.

Low power consumption mode (sleep)

- Low power consumption control is active.

- CAN transmission is stopped.

SLEEP MODE ACTIVATION

• IPDM E/R judges that the sleep-ready conditions are fulfilled when the ignition switch is OFF and none of the

conditions below are present. Then it transmits a sleep-ready signal (ready) to BCM via CAN communica-

tion.

- Outputting signals to actuators

- Switches or relays operating

- Output requests are being received from control units via CAN communication.

• IPDM E/R stops CAN communication and enters the low power consumption mode when it receives a sleep

wake up signal (sleep) from BCM and the sleep-ready conditions are fulfilled.

WAKE-UP OPERATION

• IPDM E/R changes from the low power consumption mode to the normal mode when it receives a sleep

wake-up signal (wake up) from BCM or any of the following conditions is fulfilled. In addition, it transmits a

sleep-ready signal (not-ready) to BCM via CAN communication to report the CAN communication start.

- Ignition switch ON

- An output request is received from a control unit via CAN communication.

DIAGNOSIS SYSTEM (IPDM E/R)

Diagnosis Description

INFOID:0000000012197158

AUTO ACTIVE TEST

Description

In auto active test mode, the IPDM E/R sends a drive signal to the following systems to check their operation.

• Rear window defogger

• Front wiper motor

• Parking lamp

• License plate lamp

• Tail lamp

• Side marker lamp

• Front fog lamp

• Headlamp (LO, HI)

• A/C compressor (magnet clutch)

• Cooling fan

Operation Procedure

CAUTION:

Wiper arm interferes with hood when wiper is operated while wiper arm is in the raised position.

Always perform auto active test without setting wiper arm in the raised position. Always pour water on

front windshield glass in advance to auto active test so that damage on front windshield glass surface

is prevented.

1. Turn the ignition switch OFF.
2. Turn the ignition switch ON, and within 20 seconds, press the driver door switch 10 times. Then turn the

ignition switch OFF.

CAUTION:

Close passenger door.

3. Turn the ignition switch ON within 10 seconds. After that the horn sounds once and the auto active test

starts.

CAUTION:

Engine starts when ignition switch is turned ON while brake pedal is depressed.

4. After a series of the following operations is repeated 3 times, auto active test is completed.

NOTE:

• When auto active test mode has to be cancelled halfway through test, turn the ignition switch OFF.

• When auto active test is not activated, door switch may be the cause. Check door switch. Refer to 

DLK-77,

"Component Function Check"

.

Inspection in Auto Active Test Mode

Concept of auto active test

• IPDM E/R starts the auto active test with the door switch signals transmitted by BCM via CAN communica-

tion. Therefore, the CAN communication line between IPDM E/R and BCM is considered normal if the auto

active test starts successfully.

• The auto active test facilitates troubleshooting if any systems controlled by IPDM E/R cannot be operated.
