Service bulletins

Technical service bulletins and other communications the manufacturer sent dealers about this vehicle. Ask a dealer for the full document by its number.

• 10158771Engine software On Board Diagnostic (OBD) issues will be corrected, which will aid in engine malfunction identification and proper diagnosis. In addition, Diesel Exhaust Fluid (DEF) quality sensor monitors will be corrected to proper operating function.
• 10158770Product Link models PL121/321s will stop sending data after April 6th, 2019. Date codes will appear as if coming from the past so the customer interface (UI) will not recognize those back dated messages and no data will appear in the UI.
• 10154958Certain truck models that were built with 2013 through 2015 model year CT13 engines. Engine software OBD issues will be corrected which will aid in engine malfunction identification and proper diagnosis. In addition, under certain conditions, the Selective Catalytic Reduction (SCR) system inducement schedule may not function properly and may result in an increase in regulated air pollutants. Recalibration of the Engine Control Module (ECM) and Aftertreatment Control Module (ACM) needs to be completed.
• 10142194Lower shock absorber mounting bracket may break, this is due to that the shock absorber dimension is longer than the dimension between truck frame and suspension stop. Shock absorber effectively becomes stop and breaks the lower shock mount.
