Diagnosis Description

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
  • Side marker lamps
  • License plate lamps
  • Tail lamps
  • Front fog lamps (if equipped)
  • Headlamps (LO, HI)
  • A/C compressor (magnet clutch)
  • Cooling fans

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 front door switch LH 10 times. Then turn the ignition switch OFF. CAUTION: Close front door RH.
  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-67, "Component Function Check".

Concept of auto active test

Nissan Maxima. Concept of auto active test

  • IPDM E/R starts the auto active test with the door switch signals transmitted by BCM via CAN communication.

    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.
