CAN COMMUNICATION CONTROL
When CAN communication with ECM and BCM is impossible, IPDM E/R performs fail-s
afe control. After CAN
communication recovers normally, it also returns to normal control.
If No CAN Communication Is Available With ECM
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.

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.

NOTE:
The tail lamp turns OFF when the ignition switch is turned ON.
FRONT WIPER CONTROL
IPDM E/R detects front wiper stop posit ion by a front wiper auto stop signal.
When a front wiper auto stop signal is in the conditions listed below, IPDM E/R stops power supply to wiper
after repeating a front wiper 10 second activation and 20 second 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.
DTC IndexINFOID:0000000012433275
NOTE:
The details of TIME display are as follows.
• CRNT: The malfunctions that are detected now
• 1 - 39: The number is indicated when it is normal at present and a malfunction was detected in the past. It
increases like 0 → 1 → 2 · · · 38 → 39 after returning to the normal condition whenever IGN OFF → ON. It is
fixed to 39 until the self-diagnosis results are erased if it is over 39. It returns to 0 when a malfunction is
detected again in the process.

Component Description
1. Accessory relay-2 • Accessory relay-2 is controlled by BCM.
• Accessory relay-2 supplies accessory power supply or ignition switch ACC signal to each ECU
when ignition switch is turned to ACC or ON.
• BCM compares status of accessory relay-2 control signal, and ignition switch position judged
by BCM.
2. BCM • BCM controls power distribution system.
• BCM judges ignition switch position by push-button ignition switch (push switch) and vehicle
condition.
• BCM checks ignition switch position internally.
3. Push-button ignition
switch Push-button ignition switch (push switch) is pressed, and transmits status signal to BCM and
IPDM E/R.
4. IPDM E/R • IPDM E/R detects push-button ignition switch (push switch) status, and transmits push-button
ignition switch status signal (CAN) to BCM.
• IPDM E/R receives ignition relay-1 (IPDM E/R) control signal and ignition switch ON signal
(CAN) from BCM, and controls igniti on relay-1 (built into IPDM E/R)
5. Blower relay (in fuse
block) • Blower relay is controlled by BCM.
• Blower relay supplies ignition switch ON power supply or ignition switch ON signal to air con-
ditioning system when ignition switch is turned ON.
• BCM compares status of blower relay control signal and ignition switch position judged by BCM.
6. Accessory relay-1 (in
fuse block) • Accessory relay-1 is controlled by BCM.
• Accessory relay-1 supplies accessory power supply or ignition switch ACC signal to each ECU
when ignition switch is turned ACC or ON.
• BCM compares status of accessory relay-1 control signal, and ignition switch position judged by BCM.
7. Ignition relay-2 (in fuse
block) • Ignition relay-2 is controlled by BCM.
• Ignition relay-2 supplies ignition switch ON power supply or ignition switch ON signal to each
ECU and system when ignition switch is turned ON.
• BCM compares status of ignition relay-2 control signal and ignition switch position judged by
BCM.
• BCM monitors ignition relay-2 operating status by ignition relay feedback signal.
