AUTO ACTIVE TEST
Description
In auto active test, the IPDM E/R sends a drive signal to the following systems to check their operation.
 Oil pressure warning lamp
 Rear window defogger
 Front wiper (LO, HI)
 Parking lamp
 License plate lamp
 Tail lamp
 Side marker lamp
 Front fog lamp
 Headlamp (LO, HI)
 A/C compressor (magnet clutch)
Operation Procedure
CAUTION:
Never perform auto active test in the following conditions.
 Engine is running.
 CONSULT-III is connected.
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 the ignition switch OFF.
3. Turn the ignition switch ON, and within 20 seconds, pr ess 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. Af ter that the horn sounds once and the auto active test
starts.
CAUTION:
Engine starts when ignition switch is turned ON while brake pedal is depressed.
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 has to be cancelled halfw ay through test, turn the ignition switch OFF.
 When auto active test is not activated, door swit ch may be the cause. Check door switch. Refer to DLK-117,
"ComponentFunctionCheck".
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 Oil pressure warning lamp Blinks continuously during operation of auto active test
2 Rear window defogger 10 seconds
3 Front wiper LO for 5 seconds → HI for 5 seconds

< BASIC INSPECTION >[XENON TYPE]
INSPECTION AND ADJUSTMENT
If “CAN NOT BE TESTED” is indi
cated, AFS control unit detects that the height sensor signal
changes. The levelizer adjustment is cancelled. In this case, turn the ignition switch OFF to pre-
vent the vehicle from the height change. Perform the levelizer adjustment again.
Is the levelizer adjustment completed?
YES >> GO TO 3.
NO >> Perform the levelizer adjustment again.
3.SELF-DIAGNOSIS RESULT CHECK
Perform self-diagnosis with CONSULT-III. Check that any DTC is not detected.
Is any DTC detected?
YES >> GO TO 2.
NO >> Levelizer adjustment completed

DTC No. Trouble diagnosis name DTC detection condition Possible cause
B2503 Swivel actuator [RH] AFS control unit indicates an applicable DTC when detecting any of the following conditions continuous-
ly for 2 seconds or more.
 AFS control unit-recognized swivel position differs extremely from the swivel position sensor-input
value while the swivel operating.
*
 The swivel position sensor signal does not change even though AFS control unit transmits the swivel
motor driving signal while the swivel operating
*.
 The swivel motor short and open is detected while
the swivel operating
*.
 The swivel position sensor power supply is 6 V or more, or 4 V or less.
 The swivel position sensor signal is 0.25 V or less, or 4.75 V or more. Swivel position sensor
