Overview
| MLIT filing number | 1150530 |
|---|---|
| Type | Statutory Recall (government-mandated recall) |
| Date filed | November 10, 2021 |
| Manufacturer(s) | Hino |
| Component | Computer (Exhaust Emissions/Noise) |
| Production period | April 2019 — October 29, 2021 |
| Vehicles affected | 19,090 units |
Defect
On heavy-duty trucks, the engine control computer was reprogrammed as part of the improvement measure reported on September 15, 2021 (notification number 5016). The exhaust temperature sensor fault-detection logic in that updated program is incorrect. As a result, the program may incorrectly identify a normally functioning sensor as faulty, causing the engine warning lamp (MIL) to illuminate.
Corrective action
Reprogram the engine control program on all vehicles with the corrected software.
