Concept of Auto Active Test
WARNING: This page is about a different car, the 2004 Nissan Altima. However, it is still accessible from the selected car via links, so may be relevant.
- 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.
