NHTSA's recall notice

As NHTSA's recall record states it for campaign 20V383000.

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 consequence

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.

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.
