Opacity Test
Dear Kenworth Customer,
Kenworth has released a software update that is optional for your vehicle (listed within this letter), should you choose to pay for it. The
software update may be of interest to persons who operate their vehicles in California, due to recent amendments to the Heavy Duty
Vehicle Inspection Program (HDVIP) administered by the California Air Resources Board.
All heavy-duty trucks and buses are subject to California’s anti-smoke and tampering inspections. CARB inspectors may conduct
roadside anti-smoke inspections to ensure vehicles comply with allowable levels of smoke opacity. The test procedure requires the
driver to rapidly accelerate the engine several times. The test may cause the Engine Overspeed Lamp to illuminate. Illumination of the
Engine Overspeed Lamp in these circumstances does not indicate a problem with the vehicle, but it may create confusion for the
driver or inspector. A software update is available to prevent the illumination of the Engine Overspeed Lamp during smoke opacity
tests.
The problem is…
A software calibration may cause the Engine Overspeed lamp to illuminate
during a Smoke Opacity test.
What your dealer could do…
At your expense, dealers could update the software.
What you can do …
Contact your Kenworth Dealer to schedule an appointment for repair.
If you would like this software update installed, contact a Kenworth dealership to schedule an appointment for this work. You can find
your nearest Kenworth dealer at Dealer Locator on the website www.Kenworth.com.
This software update will not be paid for by Kenworth Truck Company.
When contacting your selected Kenworth dealer, refer to campaign TIB 43-064 and the VIN listed on this letter. The work will take
approximately 1.0 hour, depending on vehicle configuration and dealer scheduling.
If you experience any difficulty in making arrangements for this repair, please contact Kenworth Customer Service at 425-8285888, provide your name, your dealer’s city and state, your phone number, your email address (optional), the last 8 digits of your
VIN, the bulletin number, and your question.
If you no longer own this vehicle, we would appreciate your advising us of the new owner if you know their name.

Cher client Kenworth,
Kenworth a lancé une mise à jour de logiciel, laquelle est optionnelle pour votre véhicule (cité à la présente), si vous décidez d’en

En Californie, tous les camions lourds et les autobus sont sujets aux inspections relatives à la fumée et à l’altération. Les inspecteurs
CARB peuvent procéder à des inspections routières contre la fumée afin de s’assurer que les véhicules sont conformes aux niveaux

peut occasionner l’illumination du témoin de survitesse du moteur. Dans de telles circonstances, l’illumination du témoin de
survitesse du moteur n’indique pas que le véhicule présente un problème mais peut créer une confusion pour le chauffeur ou
l’inspecteur. Une mise à jour du logiciel est disponible afin de prévenir l’illumination du témoin de survitesse du moteur durant les
tests d’opacité.
Le problème…
Une calibration de logiciel peut occasionner l’illumination du témoin de
survitesse du moteur durant un test d’opacité.
Ce que pourrait faire votre
concessionnaire…
Les concessionnaires pourraient procéder à la mise à jour du logiciel, à
vos frais.
Ce que vous pouvez faire…
Communiquer avec votre concessionnaire Kenworth afin de prendre
rendez-vous pour la réparation.
