VEHICLE PROXIMITY NOTIFICATION SYSTEM The Sound does not Stop when The Engine is Operated or when The Shift Lever is in P

DESCRIPTION

The vehicle approaching speaker controller receives "permission signals*" from the hybrid vehicle control ECU, and produces the warning sound from the vehicle approaching speaker assembly.

Tech Tips

*: Permission signals


  • Vehicle proximity notification system operation permitted (engine is stopped and shift lever is not in P).

  • Vehicle proximity notification system operation prohibited (engine is operating or shift lever is in P).

      Body Electrical > Vehicle Proximity Notification System > Data List
      Tester Display Measurement Item Range Normal Condition Diagnostic Note
      Permission Signal Vehicle proximity notification system permission signal OFF or ON

      OFF: Vehicle proximity notification system operation prohibited (engine is operating or shift lever is in P).

      ON: Vehicle proximity notification system operation permitted (engine is stopped and shift lever is not in P).
