This Safety Recall does not necessarily apply to all the above-mentioned vehicles, some vehicles may have been modified before delivery. The owners of the vehicles affected by this recall will be advised by a letter indicating the Vehicle Identification Number (VIN) of each vehicle concerned.
DESCRIPTION
On vehicles affected by this recall, the hazard warning lights do not comply with FMVSS 108 S6.1.5.1 because the turn signal lamps do not flash simultaneously when the hazard warning lights are activated with the ignition set to “OFF”.
The issue results from a software development error.
Therefore, a corrected software version that ensures that the hazard warning lights are fully compliant with FMVSS 108 must be installed on all potentially affected vehicles (06100191.P01 for H3-45 and 06100192.P01 for H3-45 VIP).
Please make an appointment in a Prevost Service Center or contact your Prevost Service representative to have the vehicle program upgraded. It requires VPG (Vehicle Program Generator) software.
For operators having the required equipment & software, please contact a Prevost Service representative to receive the vehicle program update file.
