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.
