AUTO ACTIVE TEST
Description
In auto active test mode, the IPDM E/R sends a drive signal to the following systems to check their operation.
Operation Procedure
NOTE: When auto active test mode has to be cancelled halfway through test, turn ignition switch OFF.
CAUTION:
Inspection in Auto Active Test Mode
When auto active test mode is actuated, the following 6 steps are repeated 3 times.
*: Outputs duty ratio of 50% for 5 seconds → duty ratio of 100% for 5 seconds on the cooling fan control module.
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.
