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
• Side marker 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, pr ess the driver door switch 10 times. Then turn the
ignition switch OFF.
4. Turn the ignition switch ON within 10 seconds. Af ter 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 halfw ay through test, turn the ignition switch OFF.
• When auto active test is not activated, door swit ch may be the cause. Check door switch. Refer to DLK-98,
"ComponentFunctionCheck" (with Intelligent Key system) or DLK-232, "ComponentFunctionCheck"
(without Intelligent Key system).
Inspection in Auto Active Test
When auto active test is actuated, the following operation sequence is repeated 3 times.
Operation se-
quence Inspection location

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.

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".

The power supply position changing operation can be performed with the following operations.
NOTE:
• When an Intelligent Key is within the detection area of inside key antenna and when Intelligent Key backside
is contacted to push-button ignition switch, it is equivalent to the operations below.
• When starting the engine, the BCM monitors under the engine start conditions:
- Brake pedal operating condition
- Selector lever position
- Vehicle speed
Vehicle speed: less than 4 km/h (2.5 MPH)
Vehicle speed: 4 km/h (2.5 MPH) or more
Emergency stop operation
• Press and hold the push-button ignition switch for 2 seconds or more.
• Press the push-button ignition switch 3 times or more within 1.5 seconds.
