Concept of Auto Active Test
-
IPDM E/R actuates auto active test mode when it receives door switch signal from BCM via CAN communication 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.
