Body Control Module: Scan Tool Testing and Procedures
-
When auto active test mode is actuated, the following seven steps are repeated three times.
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 systems controlled by IPDM E/R cannot be operated, possible cause can be easily diagnosed using auto active test.
