RELAY CONTROL SYSTEM : System Description

INFOID:0000000009266409

DESCRIPTION

IPDM E/R activates the internal control circuit to perform the relay ON-OFF control according to the input sig-

nals from various sensors and the request signals received from control units via CAN communication.

CAUTION:

IPDM E/R integrated relays cannot be removed.

POWER CONSUMPTION CONTROL SYSTEM : System Description

INFOID:0000000009266411

DESCRIPTION

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:0000000009266412

AUTO ACTIVE TEST

Description

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

• Front wiper (LO, HI)

• Parking lamp

• License plate lamp

• Tail lamp

• Front fog lamp

• Headlamp (LO, HI)

• A/C compressor (magnet clutch)

• Cooling fan

Operation Procedure

NOTE:

Never perform auto active test in the following conditions.

• Passenger door is open

• CONSULT is connected
1. Close the hood and lift the wiper arms from the windshield. (Prevent windshield damage due to wiper

operation)

NOTE:

When auto active test is performed with hood opened, sprinkle water on windshield beforehand.

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

ignition switch OFF.

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

starts.

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

• When auto active test 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-89,

"Component Function Check"

.

Inspection in Auto Active Test

When auto active test is actuated, the following operation sequence is repeated 3 times.
