Auto Active Test
EKS009XE
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, license, front fog, and parking lamps
–
Headlamps (Hi, Lo)
–
A/C compressor (magnetic clutch)
OPERATION PROCEDURE
1.
Close hood and 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, press front door switch LH 10 times. Then turn ignition
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 perform
when the auto active test cannot be performed.
INSPECTION IN AUTO ACTIVE TEST MODE
●
When auto active test mode is actuated, the following five steps are repeated three times.
Cooling fan output
MOTOR FAN
With a certain operation (1, 2, 3, 4), the cooling fan can be operated.
Headlamp relay (HI, LO)
output
EXTERNAL LAMPS
With a certain operation (OFF, HI ON, LO ON, TAIL ON, FOG ON), the
lamp relay (Low, High, Tail, Fog) can be operated.
Front fog lamp relay (FOG)
output
EXTERNAL LAMPS
With a certain operation (OFF, HI ON, LO ON, TAIL ON, FOG ON), the
lamp relay (Low, High, Tail, Fog) can be operated.
Tail lamp relay output
EXTERNAL LAMPS
With a certain operation (OFF, HI ON, LO ON, TAIL ON, FOG ON), the
lamp relay (Low, High, Tail, Fog) can be operated.
Horn output
HORN
With a certain ON-OFF operation, the horn relay can be operated.

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 the systems controlled by IPDM E/R cannot be operated, possible cause can be easily diagnosed
using auto active test.

1.
FUSE AND FUSIBLE LINK INSPECTION
●
Check that the following fusible links are not blown.
OK or NG
OK
>> GO TO 2.
NG
>> Replace fusible link.
2.
POWER CIRCUIT INSPECTION
1.
Disconnect IPDM E/R harness connector E118.

Inspection with CONSULT-II (Self-Diagnosis)
EKS009XI
CAUTION:
If a CONSULT-II is used with no connection of CONSULT-II CONVERTER, malfunctions might be
detected in self-diagnosis depending on which control unit(s) carries out CAN communication.
