Inspection Mode

NOTE: The engine is shut off when engine is at normal operating temperature and battery is fully charged and A/C is not turned on. It is necessary to put transit in inspection mode so engine will run continuously.

To put transit in inspection mode, perform the following steps within 60 seconds:

  • Ensure ignition is off and then turn ignition on.
  • Ensure transaxle is in Park and then fully depress accelerator pedal 2 times.
  • Place transaxle in Neutral and then fully depress accelerator pedal 2 times.
  • Place transaxle back in Park and then fully depress accelerator pedal 2 times.
  • Check that master warning light on instrument cluster at center of instrument panel is flashing to indicate inspection mode operation. See Fig 1. Master warning light may also be referred to as hybrid system error warning light. Turn ignition switch to START position to start engine. Engine will now start and run continuously.
