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
- Tail and parking lamps
- Front fog lamps
- Headlamps (Hi, Lo)
- A/C compressor (magnet clutch)
- Cooling fan

OPERATION PROCEDURE
1. Close hood and 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 front door switch LH ten times. Then turn ignition switch OFF.


CAUTION: Close front door RH.

4. Turn ignition switch ON.
5. When auto active test mode is actuated, horn chirps once, and 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 "Oil Pressure Warning Lamp Stays Off (Ignition Switch ON)" and "Door Switch Check" when the auto active test cannot be performed.
Refer to Lamps and Indicators - Engine / Oil Pressure Warning Lamp/Indicator / Testing and Inspection.
Testing and Inspection
Refer to Instrument Panel, Gauges and Warning Indicators / Door Switch / Testing and Inspection.

Inspection In Auto Active Test Mode
When auto active test mode is actuated, the seven steps are repeated three times.


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.
