What's wrong?
The ABS control unit on the 2021 Hino NJ8A is the brake computer for the full air brake system. It reads wheel-speed signals from toothed rings at the wheels, then uses those signals to keep the wheels from locking during hard braking. In normal operation, the software has to match the actual tooth count on the truck so the computer reads front and rear wheel speeds correctly.
On affected low-profile trucks, the control software was loaded with the wrong rear tone-ring tooth count. That mismatch made the computer think the front and rear wheels were rotating at different speeds even when the truck was moving steadily. After the fault appeared, the ABS warning lamp came on and the anti-lock function was suspended, leaving the base air brakes working without the anti-lock feature.
The warning sign is the ABS warning lamp. If that lamp comes on, the truck is telling you the ABS function has been suspended and needs dealer attention.

What's the safety risk?
A loss of ABS function increases the risk of a crash. If the ABS warning lamp comes on, the system has been suspended; slow down, leave extra stopping room, and arrange service with a Hino dealer. Repair will be free at any franchised Hino dealer once available.
What should I do?
- Check your VIN to confirm your 2021 Hino NJ8A is included in this recall.
- Watch for Hino's owner notice before scheduling the dealer software update.
- Contact a franchised Hino dealer after Hino confirms the repair is open, and ask for the ABS-ECU software update that corrects the wheel-speed dataset and keeps ABS active.
- Call Hino customer service at 1-248-699-9390 with questions and reference recall number 20V383 (Hino recall AAJS0) when you call.
- Drive with extra space for braking until the repair is complete, since loss of ABS function can increase crash risk.
What happens at the repair
