Diagnosis Description
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.
Note:
When auto active test is performed with hood opened, sprinkle water on windshield beforehand.
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.
