IPDM E/R (INTELLIGENT POWER DISTRIBUTION MODULE ENGINE ROOM)
Revision: November 20092006 QX56
Auto Active TestEKS00BN6
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 and parking lamps
–Front fog lamps
–Headlamps (Hi, Lo)
–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 10 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-92, "
Door Switch Check" when the auto active test cannot be performed.
INSPECTION IN AUTO ACTIVE TEST MODE

When auto active test mode is actuated, the following seven steps are repeated three times.
Lamp (HI, LO, TAIL, FOG)
output EXTERNAL LAMPS
With a certain operation (OFF, HI ON, LO ON, TAIL ON, FOG ON), the
lamp relay (Low, High, Tail, Fog) can be operated.
Cornering lamp output CORNERING LAMP —
Horn output HORN With a certain ON-OFF operation, the horn relay can be operated.

REMOVAL
CAUTION:

Do not attempt to repair or replace damaged direct-connect SRS component connectors. If a
driver air bag direct-connect harness connector is damaged, the spiral cable must be replaced.

Before servicing the SRS, turn ignition switch OFF, disconnect both battery cables and wait at
least 3 minutes.

When servicing the SRS, do not work from directly in front of air bag module.
1. Disconnect the negative and positive battery cables, then wait at least 3 minutes.
2. Remove the left and right side lids and bolts.
3. Lift the driver air bag module from the steering wheel.
4. Disconnect the horn connector and air bag harness, then remove the driver air bag module.

For removal/installation of the direct-connect SRS connectors, refer to SRS-7, "Direct-connect SRS
Component Connectors" .
CAUTION:

When servicing the SRS, do not work from directly in front of air bag module.

Always place air bag module with pad side facing upward.

Do not insert any foreign objects (screwdriver, etc.) into air
bag module or harness connectors.

Do not disassemble air bag module.

Do not use old bolts after removal; replace with new bolts.

Do not expose the air bag module to temperatures exceed-
ing 90 °C (194 °F).
