Concept of Auto Active Test

IPDM 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.

If any of systems controlled by IPDM E/R cannot be operated, possible cause can be easily diagnosed
using auto active test.

IPDM E/R Power/Ground Circuit InspectionNKS000EC
1. CHECK FUSE AND FUSIBLE LINK
Make sure the following fusible links or IPDM E/R fuses are not blown.
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.

Removal and Installation of IPDM E/RNKS000EE
REMOVAL
1. Remove battery. Refer to SC-7, "Removal and Installation" .
2. Remove IPDM E/R cover A. While pressing pawl on backside of
IPDM E/R cover B toward vehicle front to unlock, lift up IPDM E/
R.
3. While pressing pawls on right and left side of IPDM E/R, remove
IPDM E/R cover B from IPDM E/R.
4. Remove harness connector from IPDM E/R.
INSTALLATION
Installation is the reverse order of removal.
