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
- Front fog lamp (if equipped)
- Headlamp (LO, HI)
- A/C compressor (magnet clutch) (if equipped)
- Cooling fan
Operation Procedure
- Passenger door is open
- CONSULT is connected
- 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.
- Turn the ignition switch OFF.
- Turn the ignition switch ON, and within 20 seconds, press the driver door switch 10 times. Then turn the ignition switch OFF.
- Turn the ignition switch ON within 10 seconds. After that the horn sounds once and the auto active test starts.
- After a series of the following operations is repeated 3 times, auto active test is completed.
- 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 Inspection .
Inspection in Auto Active Test
When auto active test is actuated, the following operation sequence is repeated 3 times.
|
Operation sequence |
Inspection location |
Operation |
|
1 |
Front wiper |
LO for 5 seconds → HI for 5 seconds |
|
2 |
|
10 seconds |
|
3 |
Headlamp |
LO for 10 seconds → HI ON <=> OFF 5 times |
|
4 |
A/C compressor (magnet clutch) (if equipped) |
ON <=> OFF 5 times |
|
5 |
Cooling fan |
LO for 5 seconds → MID for 3 seconds → HI for 2 seconds |
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.
