Hino Motors Sales U.S.A. (Hino) is recalling certain 2021 NJ8A low-profile heavy trucks equipped with a full air brake system. The Anti-Lock Braking System control unit (ABS ECU) may be programmed with incorrect datasets for the tone ring teeth, causing the anti-lock braking system to mistakenly detect a difference between front and rear wheel rotation speeds resulting in deactivation of the Anti-Lock Braking function. As such, these vehicles fail to comply with Federal Motor Vehicle Safety Standard number 121, “Air Brake Systems.”
