DIAGNOSIS SYSTEM (IPDM E/R) (WITH INTELLIGENT KEY SYSTEM)

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.

Diagnosis Description

INFOID:0000000006046540

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
• Front wiper (LO, HI)
• Parking lamps
• License plate lamps
• Tail lamps
• Headlamps (LO, HI)
• A/C compressor (magnet clutch)
• Cooling fan

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, 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.

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 halfway through test, turn the ignition switch OFF.
• When auto active test is not activated, door switch may be the cause. Check door switch. Refer to 

XX-XX,

"*****"

.
