AUTO ACTIVE TEST
Description
In auto active test, the IPDM E/R sends a drive signal to the following systems to check their operation.
Operation Procedure
NOTE: Never perform auto active test in the following conditions.
1. Close the hood and lift the wiper arms from the windshield. (Prevent windshield damage due to wiper operation)
NOTE: When auto active test is performed with hood opened, sprinkle water on windshield beforehand.
2. Turn the ignition switch OFF.
3. Turn the ignition switch ON, and within 20 seconds, press the driver door switch 10 times. Then turn the ignition switch OFF.
4. Turn the ignition switch ON within 10 seconds. After that the horn sounds once and the auto active test starts.
5. After a series of the following operations is repeated 3 times, auto active test is completed.
NOTE:
Inspection in Auto Active Test
When auto active test is actuated, the following operation sequence is
repeated 3 times.
Concept of Auto Active Test
Therefore, the CAN communication line between IPDM E/R and BCM is considered normal if the auto active test starts successfully.
