Auto Active Test

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

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 wipers
- Parking lamp, license plate lamp and tail lamp
- 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, press driver's front door switch 10 times (close other door). 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: Be sure to inspect BL-35, "Check Door Switch" when the auto active test cannot be performed. Check Door Switch

INSPECTION IN AUTO ACTIVE TEST MODE






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.
