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.

DescriptionINFOID:0000000006220179
IPDM E/R operates the ignition relay when it receives
an ignition switch ON signal from BCM via CAN com-
munication.
Turn the ignition relay OFF by pressing the push-butt on ignition switch once when the vehicle speed is 4 km/
h (2.5 MPH) or less.
Turn the ignition relay OFF with the following operat ion when the vehicle speed is more than 4 km/h (2.5
MPH) or when an abnormal condition occurs in CAN communication from the combination meter (Emer-
gency OFF)
- Press and hold the push-button ignition switch for 2 seconds or more.
- Press the push-button ignition switch 3 times within 1.5 seconds.
NOTE:
The ignition relay does not turn ON for 3 seconds af ter emergency OFF even if the push-button ignition switch
is pressed.
