1. With the ignition switch OFF, connect CONSULT-II and CON-
SULT-II CONVERTER to the data link connector, and then turn
ignition switch ON.
2. Touch “START (NISSAN BASED VHCL)”.
3. Touch “IPDM E/R” on “SELECT SYSTEM” screen.
If “IPDM E/R” is not displayed. Refer toGI-50, "
CONSULT-II
Data Link Connector (DLC) Circuit".

Auto Active TestEKS00PAC
DESCRIPTION
lIn 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 wiper
–Tail lamps, front fog lamps, parking lamps and license plate lamps
–Headlamps (HI, LO)
–A/C compressor (magnetic clutch)
–Cooling fan
–Oil pressure warning lamp
OPERATION PROCEDURE
1. Close hood and front door passenger side, and then 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 driver's door switch 10 times (close other doors).
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, oil pressure warning lamp starts blinking.
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 performBL-39, "
Check Door Switch"when the auto active test cannot be performed.
Test name CONSULT-II screen display Description

IPDM E/R (INTELLIGENT POWER DISTRIBUTION MODULE ENGINE ROOM)
INSPECTION IN AUTO ACTIVE TEST MODE
When auto active test mode is actuated, the following six steps are repeated three times.
A: Oil pressure warning lamp is blinking when the auto active test operating.
Operation steps
Concept of Auto Active Test
lIPDM 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.
lIf any of the systems controlled by IPDM E/R cannot be operated, possible cause can be easily diagnosed
using auto active test.
