INSPECTION IN AUTO ACTIVE TEST MODE
When auto active test mode is actuated, the following eight steps are repeated three times.
NOTE:
Turns ON-OFF the solenoid to switch Hi/Lo. In this case, the bulb does not illuminate.
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.
