Kenworth transmission control module (TCM) may allow the engine to crank briefly even if the transmission shifter is not in neutral.
The short version
PACCAR Incorporated reported a problem with the automatic transmission control module (tcm/pcm/tecm). Here is what owners need to know.
The transmission control module (TCM) may allow the engine to crank briefly even if the transmission shifter is not in neutral. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 102, "Transmission Shift Lever Sequence/Starter Interlock/Transmission Braking Effect."
If the transmission is not in neutral when the engine begins running, there may be unintended vehicle movement, increasing the risk of a crash.
PACCAR will notify owners, and dealers will update the TCM software, free of charge.
