Sound Generator - SMART Fortwo 451 Series Introduction Into Service Manual

Sound generator

Since the electric drive system of the smart
fortwo electric drive is very quiet, especially at
low speeds, there is a risk that the vehicle may not
be noticed or may only be noticed very late by
other road users, particularly pedestrians. For
this reason, a sound generator is offered as
special equipment for the smart fortwo electric
drive.
The sound generator is located at the front under
the service flap and generates a speed-depen-
dent noise at up to approx. 30 km/h.
The sound generator consists of a control unit, an
audio output stage and a speaker. The sound
P82.62-3826-00
generator is actuated by the drivetrain control
H4/16 Electric vehicle sound generator
unit via the CAN bus.
