DIAGNOSIS SYSTEM (IPDM E/R)

Diagnosis Description


AUTO ACTIVE TEST

Description
In auto active test, the IPDM E/R sends a drive signal to the following systems to check their operation.
- Oil pressure warning lamp
- Rear window defogger
- Front wiper (LO, HI)
- Parking lamp
- License plate lamp
- Tail lamp
- Side marker lamp
- Front fog lamp
- Headlamp (LO, HI)
- A/C compressor (magnet clutch)
Operation Procedure

CAUTION:
Never perform auto active test in the following conditions.
- Engine is running.
- CONSULT is connected.
1.Close the hood and lift the wiper arms from the windshield. (Prevent windshield damage due to wiper operation)
NOTE:
When auto active test is performed with hood opened, sprinkle water on windshield beforehand.
2.Turn the ignition switch OFF.
3.Turn the ignition switch ON, and within 20 seconds, press the driver door switch 10 times. Then turn the ignition switch OFF.

CAUTION:
Close passenger door.
4.Turn the ignition switch ON within 10 seconds. After that the horn sounds once and the auto active test starts.

CAUTION:
Engine starts when ignition switch is turned ON while brake pedal is depressed.
5.The oil pressure warning lamp starts blinking when the auto active test starts.
6.After a series of the following operations is repeated 3 times, auto active test is completed.
NOTE:
- When auto active test has to be cancelled halfway through test, turn the ignition switch OFF.
- When auto active test is not activated, door switch may be the cause. Check door switch. Refer to "Component Function Check" Door Switch.
Inspection in Auto Active Test
When auto active test is actuated, the following operation sequence is repeated 3 times.





Concept of auto active test





- IPDM E/R starts the auto active test with the door switch signals transmitted by BCM via CAN communication. Therefore, the CAN communication line between IPDM E/R and BCM is considered normal if the auto active test starts successfully.
- The auto active test facilitates troubleshooting if any systems controlled by IPDM E/R cannot be operated.
