Auto Active TestEKS00PAC
DESCRIPTION
lIn 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 wiper
–Tail lamps, front fog lamps, parking lamps and license plate lamps
–Headlamps (HI, LO)
–A/C compressor (magnetic clutch)
–Cooling fan
–Oil pressure warning lamp
OPERATION PROCEDURE
1. Close hood and front door passenger side, and then 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 driver's door switch 10 times (close other doors).
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, oil pressure warning lamp starts blinking.
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 performBL-39, "
Check Door Switch"when the auto active test cannot be performed.

IPDM E/R (INTELLIGENT POWER DISTRIBUTION MODULE ENGINE ROOM)
INSPECTION IN AUTO ACTIVE TEST MODE
When auto active test mode is actuated, the following six steps are repeated three times.
A: Oil pressure warning lamp is blinking when the auto active test operating.
Operation steps
Concept of Auto Active Test
lIPDM E/R actuates auto active test mode when it receives door switch signal from BCM via CAN commu-
nication line. Therefore, when auto active test mode is activated successfully, CAN communication
between IPDM E/R and BCM is normal.
lIf any of the systems controlled by IPDM E/R cannot be operated, possible cause can be easily diagnosed
using auto active test.

Check IPDM E/R Power Supply and Ground Circuit
EKS00PAF
1.CHECK FUSES AND FUSIBLE LINK
Check for blown fuses and fusible link.
OK or NG
OK >> GO TO 2.
NG >> If fuse or fusible link is blown, be sure to eliminate cause of malfunction before installing new fuse
or fusible link.
2.CHECK POWER SUPPLY CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect IPDM E/R harness connector.
3. Check voltage between IPDM E/R harness connector and
ground.
OK or NG
OK >> GO TO 3.
NG >> Repair harness or connector.
3.CHECK GROUND CIRCUIT
1. Disconnect IPDM E/R harness connectors.
2. Check continuity between IPDM E/R harness connectors and
ground.
OK or NG
OK >> INSPECTION END
NG >> Repair harness or connector.
