Diagnosis Description
INFOID:0000000009160314
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.
• Front wiper (LO, HI)
• Parking lamps
• License plate lamps
• Side marker lamps
• Tail lamps
• Headlamps (LO, HI)
• A/C compressor (magnet clutch)
• Cooling fan (cooling fan control module)
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 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.
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 the ignition switch OFF.
CAUTION:
• If auto active test mode cannot be actuated, check door switch system. Refer to
.
• 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.
*: Outputs duty ratio of 50% for 5 seconds
→
duty ratio of 100% for 5 seconds on the cooling fan control module.

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.

BCM (BODY CONTROL MODULE) : Diagnosis Procedure
INFOID:0000000009160316
1.
CHECK FUSE AND FUSIBLE LINK
Check that the following fuse and fusible link are not blown.
Is the fuse fusing?
YES
>> Replace the blown fuse or fusible link after repairing the affected circuit if a fuse or fusible link is
blown.
NO
>> GO TO 2.
2.
CHECK POWER SUPPLY CIRCUIT
1.
Turn ignition switch OFF.
2.
Disconnect BCM connectors.
3.
Check voltage between BCM harness connector and ground.
Is the measurement value normal?
YES
>> GO TO 3.
NO
>> Repair harness or connector.
3.
CHECK GROUND CIRCUIT
Check continuity between BCM harness connector and ground.
Does continuity exist?
YES
>> INSPECTION END
NO
>> Repair harness or connector.
