Defect description
Hino Motors Sales U.S.A., Inc. (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."
Safety risk
A loss of ABS function can increase the risk of a crash.
Manufacturer remedy
Hino will notify owners, and dealers will reprogram the ABS-ECU with the corrected software. The recall began August 25, 2020. Owners may contact Hino customer service at 1-248-699-9390. Hino's number for this recall is AAJS0.
