< FUNCTION DIAGNOSIS >
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.
