Product Details
If your 2012–2021 Tesla Model S has issues like hoarse horn sound,
no response, or failure to trigger honking via the vehicle’s RC
(Remote Control) function, this CFN brand high-tone horn is the
targeted solution. As a CFN branded part (not a Tesla OEM part), it
is strictly designed to match the acoustic parameters and
installation specifications of the 2012–2021 Model S. It not only
restores the clear sound quality of the original high-tone horn but
also fully supports the vehicle’s remote honking function, ensuring
normal use in scenarios such as daily driving warnings and remote
car-finding honking.
The horn adopts a high-sensitivity sound unit, with a frequency
response range focused on the 2.5–5kHz high-tone band and a sound
pressure level of 115dB (consistent with the original). This
ensures clear penetration when honking on urban roads while
avoiding harsh noise. Whether warning pedestrians at intersections,
reminding other vehicles during highway lane changes, or forming a
stereo sound effect with a low-tone horn (sold separately), it can
restore the original acoustic experience of the 2012–2021 Model S
and complies with the national motor vehicle horn sound level
standard (GB 7258).
Tailored to the remote control system characteristics of the
2012–2021 Model S, CFN has optimized the electrical response speed
of the horn: when "remote car-finding honking" is triggered via the
Tesla mobile APP or key fob, the horn can respond quickly within
0.3 seconds without delay or interruption. Unlike ordinary
universal horns that often have issues like "no response to remote
control" or "intermittent honking," this horn can accurately match
the signal protocol of the Model S’s Body Control Module (BCM),
ensuring stable operation of the RC function.
Considering that most 2012–2021 Model S vehicles have been in use
for many years, CFN has enhanced durability in terms of materials
and structure:
- Waterproof and Dustproof Design: The horn housing is made of sealed ABS material with an IP54
protection rating, which can resist rain, car wash sprays, and dust
in the engine compartment, preventing sound quality degradation
caused by rust of internal components.
- Stable Operation in Wide Temperature Range: Within the range of -30°C (freezing winter) to 85°C (high
temperature in the engine compartment in summer), the horn coil and
diaphragm perform stably, without problems such as "no sound in
cold state" or "sound distortion in hot state" due to extreme
temperatures.
- Anti-Vibration Structure: Built-in buffer rubber pads can absorb bumpy vibrations during
vehicle driving (such as passing speed bumps or unpaved roads),
reducing diaphragm wear and extending service life (tested to be
over 5 years under normal use).
- Fits Only 2012–2021 Model S: Exclusively compatible with Tesla Model S produced from 2012 to
2021 (including all variants such as 60, 85, P85, 90D, 100D). Not suitable for post-2022 facelifted Model S (with changed
electrical interfaces and installation positions) or other Tesla
models (e.g., Model 3/Y/X). Misuse will result in failure to install or function properly.
- Direct OEM Position Installation, No Modification Needed: The horn size and installation holes perfectly match the inner
bracket of the front bumper of the 2012–2021 Model S, and it is
equipped with a 2-pin waterproof connector of original
specifications—simply replace the old horn without cutting wires or
adjusting the installation bracket. Professional installation is
recommended (the lower guard plate of the front bumper needs to be
removed, and the operating space is limited). After installation,
confirm that there is no "horn fault" prompt through the vehicle
self-inspection.
- Replacement Scenarios: Suitable for replacing the horn of the 2012–2021 Model S when
encountering the following issues: ① Weak or distorted honking
sound; ② Horn does not honk during remote car-finding; ③ Horn has
no response at all (after eliminating fuse or wiring harness
faults).
