VEHICLE PROXIMITY NOTIFICATION SYSTEM Even when Engine is Started or Transmission Shift Main Switch (P Position Switch) is Pushed, Sound does not Stop

DESCRIPTION

The vehicle approaching speaker controller receives engine oil pressure switch signals from the engine oil pressure switch assembly and P position switch signals from the transmission control ECU assembly, and produces the warning sound from the vehicle approaching speaker assembly.
