Release Date	04/17/2020
Introduction	Kenworth Truck Company has determined that certain Vehicle Model Year 2007 through 2019 C500, T440/T470, T600, T660, T680, T800, T880, and W900 vehicles manufactured from January 24, 2007 through January 31, 2018 fail to conform to the following standards: U.S. Federal Motor Vehicle Safety Standard (FMVSS) No. 121 – Air brake systems; FMVSS No. 136 – Electronic Stability Control Systems on Heavy Vehicles; Canada Motor Vehicle Safety Standard (CMVSS) No. 121 – Air brake systems; and CMVSS 136 – Electronic Stability Control Systems on Heavy Vehicles.

In the instance where the ABS/ESC ECU loses power (i.e. the fuse blows) the voltage being measured may not drop below the 25% voltage threshold, thus the ABS and/or ESC malfunction lamp will not illuminate.
