Auto Active TestINFOID:0000000001328875
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
 Parking, license plate, side marker and tail lamps
 Front fog lamps
 Headlamps (Hi, Lo)
 A/C compressor (magnetic clutch)
 Cooling fan
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, pre ss drivers 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 chir ps 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:
Be sure to inspect BL-38, "
Check Door Switch" when the auto active t est cannot be performed.
INSPECTION IN AUTO ACTIVE TEST MODE
When auto active test mode is actuated, the following eight steps are repeated three times.
Front wiper (HI, LO) operation FRONT WIPER With a certain operation (Off, Hi, Lo),
the front wiper relay (Lo, Hi) can
be operated.
Cooling fan operation MOTOR FAN With a certain operation (1, 2, 3, 4), the cooling fan can be operated.
Lamp (HI, LO, FOG) opera-
tion LAMPSWith a certain operation (Off, Hi, Lo, Fog), the lamp relay (Lo, Hi, Fog)
can be operated.
Cornering lamp operation CORNERING LAMP
NOTE—
Horn operation HORN With a certain On-Off operation, the horn relay can be operated. Test item CONSULT-III screen display Description

Concept of Auto Active Test
 IPDM E/R actuates auto active test mode when it re ceives door switch signal from BCM via CAN communi-
cation 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.

When power is supplied, the sunroof can be operated.
The retained power operation is canceled when the driver or passenger side door is opened.
RAP signal period can be changed by CONSULT-III. Refer to RF-15, "
CONSULT-III Function (BCM)".
ANTI-PINCH FUNCTION
The CPU of sunroof motor monitors the sunroof motor operation and the sunroof position (fully-closed or
other) by the signals from sunroof motor.
When sunroof motor detects an interruption during the following slide close and tilt down operation, sunroof
switch controls the motor for open and the sunroof will operate until full up position (when tilt down operate) or
125 mm (4.92 in) or more in an open direction (when slide close operate).
 close operation and tilt down when ignition switch is in the ON position.
 close operation and tilt down during retained power operation.
MEMORY RESET PROCEDURE
1. Please observe the following instructions while confirming the sunroof operation.
NOTE:
Do not disconnect the electronic power while the sunroof is operating or within 5 seconds after the sunroof
stops. (to wipe-out the memory of lid position and operating friction.)
2. Initialization of system should be conducted after the following conditions.
 When the battery is out or connector is disconnected wh ile sunroof is operating or within 5 seconds after
sunroof stops.
 When the sunroof motor is changed.
 When an emergency handle is used.
 When the sunroof does not operate normally. (Incomplete initialization conditions)
INITIALIZATION PROCEDURE
If the sunroof does not close or open automatically, us e the following procedure to return sunroof operation to
normal.
1. Close the sunroof if it is not in the closed positi on. It may be necessary to repeatedly push the switch to
close the sunroof.
2. Press and hold the TILT UP switch. Do not release the switch, keep pressure on it. After 10 seconds of
depressing, the sunroof will tilt up, then stop. Release the button.

system and power sunroof system (if equipped). Those systems can be operated when turning on
“RETAINED PWR” on CONSULT-III screen even if the ignition switch is turned OFF.
NOTE:
During this test, CONSULT-III can be operated with ignition switch in OFF position. “RETAINED
PWR” should be turned ON or OFF on CONSULT-III screen when ignition switch is ON. Then turn
ignition switch OFF to check retained power operation. CONSULT-III might be stuck if “RETAINED
PWR” is turned to ON or OFF on CONSULT- III screen when ignition switch is OFF.
