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.

• Rear window defogger

• Front wiper motor

• Parking lamp

• License plate lamp

• Tail lamp

• Front fog lamp

• Side marker lamp

• Headlamp (LO, HI)

Operation Procedure

NOTE:

Never perform auto active test in the following conditions.

• CONSULT is connected.

• Passenger door is open.
1. Turn the power switch OFF.
2. Turn the power switch ON, and within 20 seconds, press the driver door switch 10 times. Then turn the

power switch OFF.

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

starts.

NOTE:

Never depress brake pedal while operating power switch so that auto active test is not activated.

4. 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 the power switch OFF.

• When auto active test is not activated, door switch may be the cause. Check door switch. Refer to 

DLK-102,

"Component Function Check"

.

Inspection in Auto Active Test Mode

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

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.
