How to Switch Diagnostic Test Mode

WARNING: This page is about a different car, the 2010 Infiniti FX35. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
  • It is better to count the time accurately with a clock.
  • It is impossible to switch the diagnostic mode when an accelerator pedal position sensor circuit has a malfunction.
  • ECM always returns to Diagnostic Test Mode I after the ignition switch is turned OFF.
