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.
- Front wiper (LO, HI)
- Parking lamp
- License plate lamp
- Tail lamp
- Side marker lamp
- Front fog lamp
- Headlamp (LO, HI)
- Cooling fan (cooling fan control module)
Operation Procedure

CAUTION:
Wiper arm interferes with food when wiper is operated while wiper arm is in the raised position.
Always perform auto active test without setting wiper arm in the raised position. Always pour water on front windshield glass in advance to auto active test so that damage on front windshield grass surface is prevented.
NOTE:
Never perform auto active test in the following condition.
- CONSULT is connected
- Passenger door is open
1.Turn the ignition switch OFF.
2.Turn the ignition switch ON, and within 20 seconds, press the front door switch (driver side) 10 times.
Then turn the ignition switch OFF.
NOTE:
Within 5 seconds after ignition switch is turned to the ON position and when driver door switch is pressed
6 times or more within 4 seconds, self-diagnosis function for BOSE amp. activates and speaker sounds.
After waiting for 5 seconds or more after ignition switch is turned to the ON position and when driver door switch is operated, self-diagnosis function for BOSE amp. does not activate.
3.Turn the ignition switch ON within 10 seconds. After that the horn sounds once and the auto active test starts.
NOTE:
Engine starts when ignition switch is turned ON while brake pedal is depressed.
4.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. Door Switch.
Inspection in Auto Active Test
When auto active test is actuated, the following 4 steps are 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.
