Auto Active Test
AKS00A4E
DESCRIPTION
●
In auto active test mode, operation inspection can be performed when IPDM E/R sends a drive signal to
the following systems:
–
Rear window defogger
–
Front wipers
–
Tail and parking lamps
–
Front fog lamps
–
Headlamps (Hi, Lo)
–
A/C compressor (magnetic clutch)
–
Cooling fan
OPERATION PROCEDURE
1.
Close hood front door RH and lift wiper arms away from windshield (to prevent glass damage by wiper
operation).
NOTE:
When auto active test is performed with hood opened, sprinkle water on windshield beforehand.
2.
Turn ignition switch OFF.
3.
Turn ignition switch ON and, within 20 seconds, open and close 10 times of front door LH. Then turn igni-
tion switch OFF.
4.
Turn ignition switch ON within 10 seconds after ignition switch OFF.
5.
When auto active test mode is actuated, horn chirps once.
6.
After a series of operations is repeated three times, auto active test is completed.
NOTE:
When auto active test mode has to be cancelled halfway, turn ignition switch OFF.
CAUTION:
Be sure to inspect
when the auto active test cannot be performed.
INSPECTION IN AUTO ACTIVE TEST MODE
●
When auto active test mode is actuated, the following eight steps are repeated three times.
NOTE:
Turns ON-OFF the solenoid to switch Hi/Lo. In this case, the bulb does not illuminate.

Concept of Auto Active Test
●
IPDM E/R actuates auto active test mode when it receives door switch signal from BCM via CAN commu-
nication line. Therefore, when auto active test mode is activated successfully, CAN communication
between IPDM E/R and BCM is normal.
●
If any of systems controlled by IPDM E/R cannot be operated, possible cause can be easily diagnosed
using auto active test.
