AUTO ACTIVE TEST
Description
In auto active test, the IPDM E/R sends a drive si
gnal to the following systems to check their operation.
Oil pressure warning lamp
Rear window defogger
Front wiper (LO, HI)
Parking lamp
License plate lamp
Tail lamp
Side marker lamp
Front fog lamp
Headlamp (LO, HI)
A/C compressor (magnet clutch)
Operation Procedure
CAUTION:
Never perform auto active test in the following conditions.
Engine is running.
CONSULT-III 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.
CAUTION:
Close passenger door.
4. Turn the ignition switch ON within 10 seconds. Af ter that the horn sounds once and the auto active test
starts.
CAUTION:
Engine starts when igniti on switch is turned ON while brake pedal is depressed.
5. The oil pressure warning lamp starts blinking when the auto active test starts.
6. 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 swit ch may be the cause. Check door switch. Refer to DLK-117,
"ComponentFunctionCheck".
Inspection in Auto Active Test
When auto active test is actuated, the following operation sequence is repeated 3 times.
Operation
sequence Inspection location Operation
1 Oil pressure warning lamp Blinks continuously during operation of auto active test
2 Rear window defogger 10 seconds
3 Front wiper LO for 5 seconds → HI for 5 seconds

PRECAUTIONS
5. When the repair work is completed, re-connect bot
h battery cables. With the brake pedal released, turn
the push-button ignition switch from ACC position to ON position, then to LOCK position. (The steering
wheel will lock when the push-button igniti on switch is turned to LOCK position.)
6. Perform self-diagnosis check of all control units using CONSULT-III.

EM : System DescriptionINFOID:0000000006220197
SYSTEM DESCRIPTION
PDS (POWER DISTRIBUTION SYSTEM) is the system that BCM controls with the operation of the push-
button ignition switch and performs the power distributi on to each power circuit. This system is used instead
of the mechanical power supply changing mechanism wit h the operation of the conventional key cylinder.
The push-button ignition switch can be operated when Intelligent Key is in the following condition. Refer to Engine Start Function for details.
- Intelligent Key is in the detection area of the inside key antenna.
- Intelligent Key backside is contact ed 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 follo wing relays to supply power to each power circuit.
- Ignition relay (inside IPDM E/R)
- Ignition relay-1
- ACC relay
- Blower 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 near the push-button ignition
switch.
BATTERY SAVER SYSTEM
When all the following conditions are met for 60 minutes, the battery saver system will cut off the power supply
to prevent battery discharge.
The ignition switch is in the ACC position
All doors are closed
Selector lever is in the P position
Reset Condition of Battery Saver System
In order to prevent the battery from discharging, the battery saver system will cut off the power supply when all
doors are closed, the selector lever is on P position and t he ignition switch is left on ACC position for 1 hour. If
any of the following conditions are met the battery saver system is released and the steering will change auto-
matically to lock position from OFF position.
Opening any door
Operating with door request switch on door lock
Operating with Intelligent Key on door lock
Press push-button ignition switch and ignition swit ch will change to ACC position from OFF position.

STEERING LOCK OPERATION
Steering is locked by steering lock unit when ignition switch
is in the OFF position, selector lever is in the P
position and any of the following conditions are met.
Opening door
Closing door
Door is locked with door request switch
Door is locked with Intelligent Key
POWER SUPPLY POSITION CHANGE TABLE BY PUSH-BUTTON IGNITION SWITCH OPERA-
TION
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
