Auto Active TestEKS00JLN
DESCRIPTION

In auto active test mode, operation inspection can be performed when IPDM E/R sends a drive signal to
the following systems:
–Rear window defogger
–Front wipers
–Tail, license and parking lamps
–Daytime lamp system (Canada only)
–Front fog lamps
–Headlamps (High, Low)
–A/C compressor (magnet clutch)
–Cooling fan
OPERATION PROCEDURE
1. Close hood and front door RH, and lift wiper arms away from windshield (to prevent glass damage by
wiper operation).
NOTE:
When auto active test is performed with hood opened, sprinkle water on windshield beforehand.
2. Turn ignition switch OFF.
3. Turn ignition switch ON and, within 20 seconds, press front door switch LH 20 times. Then turn ignition
switch OFF.
4. Turn ignition switch ON within 10 seconds after ignition switch OFF.
5. When auto active test mode is actuated, horn chirps once.
6. After a series of operations is repeated three times, auto active test is completed.
NOTE:
When auto active test mode has to be cancelled halfway, turn ignition switch OFF.
CAUTION:
Be sure to perform BL-40, "
Door Switch Check" when the auto active test cannot be performed.
Cooling fan output MOTOR FANWith a certain operation (1, 2, 3, 4), the cooling fan relays can be oper-
ated.
Horn output HORN With a certain ON-OFF operation, the horn relay can be operated.Test name CONSULT-II screen display Description

3. Place the steering wheel in the straight ahead position.
4. Release the driver air bag module retaining clips RH/LH.

Insert suitable 4mm - 6mm blunt tool (A) through LH access
hole on back side of steering wheel (1) and contact retaining
clip.
CAUTION:
Do not use sharp edged objects such as screwdrivers to
release driver air bag module from steering wheel, SRS
components may be unintentionally damaged.

Press tool inward with sufficient force on retaining clip (1) to
release LH pawl of driver air bag module from steering wheel.

Repeat for RH pawl of driver air bag module from steering
wheel.

Tilt top edge away from steering wheel, then lift upward
releasing lower pawl of driver air bag module from steering
wheel.
5. Disconnect driver air bag module connectors (1) and horn con-
nector (2).

For removal/installation of the direct-connect SRS connec-
tors, refer to SRS-8, "
Direct-connect SRS Component Con-
nectors" .
INSTALLATION
Installation is in the reverse order of removal.

For removal/installation of the direct-connect SRS connectors, refer to SRS-8, "Direct-connect SRS Com-
ponent Connectors" .

If driver air bag module is being replaced due to deployment, spiral cable must also be replaced. Refer to
SRS-44, "
SPIRAL CABLE" .

After the work is completed, perform self-diagnosis to check that no malfunction is detected. Refer to
SRS-21, "
SRS Operation Check" .
