In the event that the Anti-lock Brake System (ABS) loses battery and/or ignition power to the controller, the dash warning light for the ABS may not illuminate to warn the driver of the loss of ABS. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 121, "Air Brake Systems," and 136, "Electronic Stability Control System on Heavy Vehicles."

Consequence

If the driver unknowingly operates the vehicle without the ABS functioning, there would be an increased risk of a crash.

PACCAR will notify owners, and dealers will update the NAMUX software within the cab control module, free of charge. PACCAR issued owners an interim notification on June 4, 2020.
