Kenworth exterior lighting switch may fail, resulting in the hazard lights and the instrument display back-light brightness adjustment not functioning.
The short version
PACCAR Incorporated reported a problem with the hazard flashing warning lights switch. Here is what owners need to know.
The exterior lighting switch may fail, resulting in the hazard lights and the instrument display back-light brightness adjustment not functioning. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) numbers 101, "Control and Displays" and 108, "Lamps, Reflective Devices and Associated Equipment."
Inoperative hazard lights cannot alert other drivers as intended. In addition, the inability to adjust the brightness on the instrument panel display can make it difficult to see critical safety information or distract the driver.
Take it to a dealer — they will update the vehicle cab controller unit (VECU) software, free of charge.
