Auto Active Test

WARNING: This page is about a different car, the 2012 Nissan Pathfinder. However, it is still accessible from the selected car via links, so may be relevant.

Description

In auto active test mode, the IPDM E/R sends a drive signal to the following systems to check their operation.

Operation Procedure

  1. Close the hood and front door RH, and lift the wiper arms from the windshield (to prevent windshield damage due to wiper operation).
    NOTE: When auto active test is performed with hood opened, sprinkle water on windshield before hand.
  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.
  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 ignition switch OFF.
CAUTION:
  • If auto active test mode cannot be actuated, check door switch system. Refer to "DESCRIPTION " (with Intelligent Key system), "DESCRIPTION " (without Intelligent Key system).
  • Do not start the engine.

Inspection in Auto Active Test Mode

When auto active test mode is actuated, the following 7 steps are repeated 3 times.
