afe control. After CAN

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.

• 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.

SYSTEM DIAGRAM
SYSTEM DESCRIPTION
• PDS (POWER DISTRIBUTION SYSTEM) is the system that BCM contro ls with the operation of the push-
button ignition switch and performs the power distribution to each power circuit. This system is used instead
of the mechanical power supply changing mechanism wi th the operation of the conventional key cylinder.
• The push-button ignition switch can be operated when Intelligent Key is in the following condition:
- Intelligent Key is in the detection area of the inside key antenna.
- Intelligent Key backside is contacted to push-button ignition switch.
• The push-button ignition switch operation is input to BCM as a signal. BCM changes the power supply posi-
tion according to the status and operates the following relays to supply power to each power circuit:
- Ignition relay-1
- Ignition relay-2
- Accessory relay-1
- Accessory relay-2
- Blower motor relay NOTE:
The engine switch operation changes due to the conditions of brake pedal, selector lever and vehicle speed.
• The power supply position can be confirmed with the light ing of the indicators in the push-button ignition
switch.
IGNITION BATTERY SAVER SYSTEM
When all the following conditions are met for a period of time, the battery saver system will turn off the power
supply (ignition switch ON/ACC → OFF) to prevent battery discharge.
• Ignition switch is in the ACC or ON position
• Turn signal lamp is not in operation
• Selector lever is in the P (park) position
Reset Condition of Igniti on Battery Saver System
If any of the following conditions are met, the battery saver system is released.
• Ignition switch is not in the ACC or ON position
• Turn signal lamp is in operation
• Selector lever is not in the P (park) position
NOTE:
The ignition battery saver system can be temporarily di sabled, without using CONSULT, to prevent it from
functioning when performing trouble diagnosis. Refer to PCS-53, "
Work Procedure".
