[IPDM E/R (WITH I-KEY)]

DIAGNOSIS SYSTEM (IPDM E/R)

Concept of Auto Active Test

• IPDM E/R starts the auto active test with the door switch signals transmitted by BCM via CAN communica-

tion. Therefore, the CAN communication line between IPDM E/R and BCM is considered normal if the auto

active test starts successfully.

• The auto active test facilitates troubleshooting if any systems controlled by IPDM E/R cannot be operated.
