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

    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.

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.
