Diagnosis Description
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
CAUTION: Close front door RH.
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.

Checking engine coolant level
Check the coolant level in the reservoir when
the engine is cold. If the coolant level is below
the MIN level B , add coolant to the MAX level
A . If the reservoir is empty, check the coolant
level in the radiator when the engine is cold. If
there is insufficient coolant in the radiator, fi ...
