Diagnosis Description

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 low warning indicator

• Oil pressure gauge

• Rear window defogger

• Front wipers

• Tail, license and parking lamps

• Front fog lamps (if equipped)

• Headlamps (Hi, Lo)

• A/C compressor (magnetic clutch)

• Cooling fan

Operation Procedure

1. Close the hood and front door RH, and lift the wiper arms from the windshield (to prevent windshield dam-

age due to wiper operation).

NOTE:

When auto active test is performed with hood opened, sprinkle water on windshield before hand.

2. Turn ignition switch OFF.
3. Turn the ignition switch ON and, within 20 seconds, press the front door switch LH 10 times. Then turn the

ignition switch OFF.

4. Turn the ignition switch ON within 10 seconds. After that the horn sounds once and the auto active test

starts.

5. 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-56, "Descrip-

tion"

 (with Intelligent Key system), 

DLK-229, "Description"

 (without Intelligent Key system).

• Do not start the engine.

Inspection in Auto Active Test Mode

When auto active test mode is actuated, the following 7 steps are repeated 3 times.

DIAGNOSIS SYSTEM (IPDM E/R)

Concept of auto active test

• IPDM E/R starts the auto active test with the door switch signals transmitted by BCM via CAN communica-

tion. 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.
