The BCM records the following condition at the moment a particular DTC is detected.
• Vehicle Speed
• Odo/Trip Meter
• Vehicle Condition (BCM detected condition)

IGN Counter

IGN counter indicates the number of times that ignition switch is turned ON after DTC is detected.
• The number is 0 when a malfunction is detected now.
• The number increases like 1

Operation

Description

FRONT WIPER

Hi

Transmits the front wiper request signal (HI) to IPDM E/R with CAN communication to
operate the front wiper HI operation.

Lo

Transmits the front wiper request signal (LO) to IPDM E/R with CAN communication to
operate the front wiper LO operation.

INT

Transmits the front wiper request signal (INT) to IPDM E/R with CAN communication to
operate the front wiper INT operation.

Off

Stops transmitting the front wiper request signal to stop the front wiper operation.

HEADLAMP WASHER

On

Transmits the headlamp washer request signal to IPDM E/R with CAN communication to
operate the headlamp washer operation.

DIAGNOSIS SYSTEM (IPDM E/R)

Diagnosis Description

INFOID:0000000003941292

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,

"Component Function Check"

.

• 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.

< FUNCTION DIAGNOSIS >

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.
