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.
NOTE:
To prevent damage to the parts, IPDM E/R integrated relays cannot be removed.

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.

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 PROTECTION FUNCTION
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.
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.
STARTER MOTOR PROTECTION FUNCTION
IPDM E/R turns OFF the starter control relay to protect the starter motor when the starter control relay remains
active for 90 seconds.

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 acti-
vated while the front wiper is set in the INT/AUTO 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 acti-
vated while front wiper motor is operated and wiper stop in the other than stop position.

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.

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.
• Oil pressure warning lamp
• Front wiper (LO, HI)
• Parking lamp
• License plate lamp
• Side maker 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.
• CONSULT is connected
• Passenger door is open
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 front door switch (driver side) 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
Inspection in Auto Active Test Mode
When auto active test mode is actuated, the following 6 steps are repeated 3 times.

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.
