P Concept of Auto Active Test
• IPDM E/R actuates auto active test mode when it receives door switch signal from BCM via CAN communi-
cation line. Therefore, when auto active test mode is activated successfully, CAN communication between
IPDM E/R and BCM is normal.
• If any of the systems controlled by IPDM E/R cannot be operated, possible cause can be easily diagnosed
using auto active test.

PIPDM E/R Power/Ground Circuit InspectionINFOID:0000000001704704
1.FUSE AND FUSIBLE LINK INSPECTION
Check that the following fusible links or IPDM E/R fuses are not blown.
OK or NG
OK >> GO TO 2.
NG >> Replace fuse or fusible link.
2.POWER CIRCUIT INSPECTION
1. Turn ignition switch OFF.
2. Disconnect IPDM E/R harness connector E42.
3. Check voltage between IPDM E/R harness connector E42 terminals 1, 2 and ground.
