Auto Active Test
WARNING: This page is about a different variant/trim than selected.
Description
In auto active test mode, the IPDM E/R sends a drive signal to the following systems to check their operation.
- Oil pressure warning lamp
- Front wiper (LO, HI)
- Parking lamps
- License plate lamps
- Side maker lamps
- Tail lamps
- Front fog lamps
- Headlamps (LO, HI)
- A/C compressor (magnet clutch)
- Cooling fan (cooling fan control module)
Operation Procedure
- 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 front door switch (driver side) 10 times. Then turn the ignition switch OFF.CAUTION: Close passenger door.
- Turn the ignition switch ON within 10 seconds. After that the horn sounds once and the auto active test starts.
- The oil pressure warning lamp starts blinking when the auto active test starts.
- After a series of the following operations is repeated 3 times, auto active test is completed.
NOTE:
When auto active test mode has to be cancelled halfway through test, turn the ignition switch OFF.
CAUTION:
- If auto active test mode cannot be actuated, check door switch system. Refer to "COMPONENT FUNCTION CHECK ".
- Do not start the engine.
Inspection in Auto Active Test Mode
When auto active test mode is actuated, the following 6 steps are repeated 3 times.
| Operation sequence | Inspection location | Operation | ||
|---|---|---|---|---|
| 1 | Oil pressure warning lamp | Blinks continuously during operation of auto active test | ||
| 2 | Front wiper | LO for 5 seconds → HI for 5 seconds | ||
| 3 |
|
10 seconds | ||
| 4 | Headlamps | LO <==> HI 5 times | ||
| 5 | A/C compressor (magnet clutch) | ON <==> OFF 5 times | ||
| 6(1) | Cooling fan | MID for 5 seconds → HI for 5 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.
