Auto Active TestNKS004E7
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 wiper (LO, HI)
Tail lamps, parking lamps and license plate lamps
Front fog lamps
Headlamps (LO, HI)
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, horn chirps once. 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:
Never start the engine.
If the engine starting operation is made, delete DTC on the self-diag results of CONSULT-II.
Refer to BL-79, "
CONSULT-II Application Items" .
Be sure to inspect GW-50, "Check door Switch" when the auto active test cannot be performed.

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.

CONSULT-II Function (BCM)NIS0023V
CONSULT-II can display each diagnostic item using the diagnostic test modes shown following.
CONSULT-II START PROCEDURE
Refer to GI-38, "CONSULT-II Start Procedure" .
ACTIVE TEST
WORK SUPPORT
DATA MONITOR
BCM diagnostic test item Check item diagnostic test mode Content
RETAINED PWRWork support Changes setting of each function.
Data monitor Displays the input data of BCM in real time.
Active test Gives a drive signal to a load to check the operation.
Test Item Description
RETAINED PWRThis test is able to supply RAP signal (power) from BCM (body control module) to power window
system and power sunroof system (if equipped). Those systems can be operated when turning on
“RETAINED PWR” on CONSULT-II screen even if the ignition switch is turned OFF.
NOTE:
During this test, CONSULT-II can be operated with ignition switch in “OFF” position. “RETAINED
PWR” should be turned “ON” or “OFF” on CONSULT-II screen when ignition switch is ON. Then
turn ignition switch OFF to check retained power operation. CONSULT-II might be stuck if
“RETAINED PWR” is turned to “ON” or “OFF” on CONSULT-II screen when ignition switch is OFF.
Work item Description
RETAINED PWRRap signal’s power supply period can be changed by mode setting. Selects rap signal’s power
supply period between three steps
MODE1 (45 sec.) / MODE2 (OFF) / MODE 3 (2 min.).
