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

Diagnosis Description

INFOID:0000000010288768

AUTO ACTIVE TEST

Description

In auto active test, the IPDM E/R sends a drive signal to the following systems to check their operation.

• Front wiper (LO, HI)

• Parking lamp

• License plate lamp

• Tail lamp

• Front fog lamp (if equipped)

• Headlamp (LO, HI)

• A/C compressor (magnet clutch)

• Cooling fan

Operation Procedure

NOTE:

Never perform auto active test in the following conditions.

• Passenger door is open

• CONSULT 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.

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 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 

DLK-103,

"Component Inspection"

.

Inspection in Auto Active Test

When auto active test is actuated, the following operation sequence is repeated 3 times.

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.
