Auto Active Test

IPDM E/R (INTELLIGENT POWER DISTRIBUTION MODULE ENGINE ROOM)


Auto Active Test


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)
- Parking, license plate and tail 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 Self-Diagnostic Result of CONSULT-III. Refer to Consult-III Functions (Intelligent Key).
- Be sure to inspect Check Door Switch when the auto active test cannot be performed.

INSPECTION IN AUTO ACTIVE TEST MODE
When auto active test mode is actuated, the following eight steps are repeated three times.





(A): Oil pressure warning lamp is blinking when the auto active test operating.






Concept of Auto Active Test





- IPDM E/R actuates auto active test mode when it receives door switch signal from BCM via CAN communication 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.
