IPDM E/R (INTELLIGENT POWER DISTRIBUTION MODULE ENGINE ROOM)
NOTE:
This item is displayed, but cannot be tested.
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

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 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.
