PCS-12 < SYSTEM DESCRIPTION > [IPDM E/R] DIAGNOSIS SYSTEM (IPDM E/R) Concept of auto active test • IPDM E/R starts the auto active test with the door switch signals transmitted by BCM via CAN communica- tion. Therefore, the CAN communication line between IPDM E/R and BCM is considered normal if the auto active test starts successfully. • The auto active test facilitates troubleshooting if any systems controlled by IPDM E/R cannot be operated.
