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 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.
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.

• Tail lamp
• Side marker 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.
• The status is held at service position if the fail-safe control is activated while the service position function is
operating.

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
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
"POWER GENERATION VOLTAGE VARIABLE CONTROL SYSTEM : System Diagram"
.

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.
