AUTO ACTIVE TEST
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
 Tail lamps
 Front fog lamps
 Headlamps (LO, HI)
 A/C compressor (magnet clutch)
 Cooling fan
Operation Procedure
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 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.
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 mode has to be cancelled halfway through test, turn ignition switch OFF.
CAUTION:
 If auto active test mode cannot be actuated, check door switch system. Refer to DLK-57,
"ComponentFunctionCheck".
 Do not start the engine.
Inspection in Auto Active Test Mode
When auto active test mode is actuated, the following 5 steps are repeated 3 times.

DTC CONFIRMATION PROCEDURE
1.ERASE DTC
Erase DTC memory of HEADLAMP LEVELIZER with self-diagnosis of CONSULT-III.
>> GO TO 2.
2.DTC CONFIRMATION
1. Start the engine.
2. Drive the vehicle for 5 minutes or more.
3. Perform self-diagnosis of CONSULT-III.
Is B2083 detected?
YES >> Refer to EXL-41, "Diagnosis Procedure".
NO >> Refer to GI-35, "
Intermittent Incident".
Diagnosis ProcedureINFOID:0000000003805607
1.CHECK AUTO LEVELIZER CONTROL UNIT INSTALLATION CONDITION
Check the mounting part of auto levelizer control unit and its link for looseness and deformation.
Is it properly installed?
YES >> Replace the auto levelizer control unit.
NO >> Install auto levelizer control unit properly.
DTC detection condition DTC erase conditions Possible causes
When vehicle speed is 5 km/h (3.1 MPH) or more, the auto levelizer
control unit cannot detect any changes of the sensor lever angle for
5 minutes or more.Ignition switch OFF Auto levelizer control unit

Diagnosis ProcedureINFOID:0000000003805615
1.CHECK VEHICLE SPEED SIGNAL INPUT WITH CONSULT-III
1. Turn ignition switch ON.
2. Select "SPEED SIG" of HEADLAMP LEVELIZER data monitor item.
3. While driving at 40 km/h (25 MPH), check the monitor status.
Is the measurement value normal?
YES >> Replace the auto levelizer control unit.
NO >> GO TO 2.
2.CHECK VEHICLE SPEED SIGNAL INPUT
1. Turn ignition switch OFF.
2. Disconnect the auto levelizer control unit connector.
3. Turn ignition switch ON.
4. While driving at 40 km/h (25 MPH), check the voltage between the auto levelizer control unit harness con-
nector and the ground.
