What's wrong?
The engine control module on the 2023 Hino NJ7A and NV7A is the computer that manages engine operation. It receives power from the truck battery through a fused circuit, then sends commands that keep fuel, timing, and engine operation working while the truck runs.
On affected trucks, the ECM was built with damage linked to a supplier soldering fixture. A screw in that fixture moved out of position during production and pushed an electrolytic capacitor frame into the printed circuit board inside the module. That contact can create an internal short circuit. If the ECM shorts, it can shut the engine down unexpectedly.
There is no warning sign before failure. The truck can be running normally, then lose engine operation if the short circuit occurs.
Who's affected?
NJ7A and NV7A trucks share the same engine control module component in this recall.

What's the safety risk?
An unexpected engine shut down can leave the driver without normal power while the vehicle is moving, which increases the risk of a crash. There is no warning sign before failure, so schedule the ECM replacement soon and use extra caution until it is done. Repair is free at any franchised Hino dealer.
