NOTE:
When auto active test mode has to be cancelled halfway, turn ignition switch OFF.
CAUTION:
Be sure to perform BL-44, "
Door Switch Check (Hatchback)" or BL-47, "Door Switch Check
(Sedan)" when the auto active test cannot be performed.
INSPECTION IN AUTO ACTIVE TEST MODE
When auto active test mode is actuated, the following six steps are repeated three times.
(A): Oil pressure warning lamp is blinking when the auto active test is operating.

IPDM E/R (INTELLIGENT POWER DISTRIBUTION MODULE ENGINE ROOM)
Concept of Auto Active Test
• IPDM E/R actuates auto active test mode when it re ceives door switch signal from BCM via CAN communi-
cation line. Therefore, when auto active test mode is activated successfully, CAN communication between
IPDM E/R and BCM is normal.
• If any of the systems controll ed by IPDM E/R cannot be operated, possible cause can be easily diagnosed
using auto active test.
