- Summary
- 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."
- Consequence
- A loss of ABS function can increase the risk of a crash.
- 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.
- Notes
- Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.

Vehicles covered
As listed by NHTSA. A recall usually covers only some vehicles of each model and year, often a production date range.
Has your Hino been repaired?
Recalls here come from NHTSA’s records for the model and year. Not every vehicle of a model is included in every recall, and this site can’t see whether a repair has been done. Only a VIN lookup can tell you that.
NHTSA’s VIN search doesn’t show recalls that were already repaired, recalls more than 15 years old, or some small manufacturers’ recalls. A Hino dealer can also check your VIN. Recall repairs are free.
