Overview
| MLIT filing number | 1153912 |
|---|---|
| Type | Statutory Recall (government-mandated recall) |
| Date filed | October 18, 2023 |
| Manufacturer(s) | Hino, Toyota |
| Component | Computer (powertrain control) |
| Production period | July 2011 — January 17, 2023 |
| Vehicles affected | 929 units |
Defect
In the automated mechanical transmission control computer of small hybrid trucks, the control program for the automatic clutch actuator motor and the motor replacement interval are improperly configured. When the motor is near the end of its service life, two conditions may occur. First, the motor check process takes excessive time, causing a false fault detection; clutch operation is suspended, a warning lamp illuminates, and the vehicle becomes inoperable. Second, when the vehicle is parked in gear, the clutch may fail to disengage at startup, preventing the engine from starting.
Corrective action
On all vehicles, reprogram the control computer with the corrected/updated software. After reprogramming, replace any motor on which a motor replacement warning is displayed with a new unit (one time only).

状況
小型ハイブリッドトラックの機械式自動変速機制御コンピュータにおいて、自動クラッチ作動用モータの制御プログラムおよびモータ交換時期の設定が不適切なため、モータが寿命に近い状態の場合、１．モータチェックに時間が掛かり異常と誤検知して、クラッチ作動を停止し、警告灯が点灯するとともに走行不能となるおそれがある。２．ギヤを入れて駐車した場合、始動時にクラッチが切れず、エンジン始動不能となるおそれがある。
改善措置
全車両、制御プログラムを対策プログラムに書き換える。また、当該制御プログラム書き換え後に、モータを交換警報が表示したものから新品に交換する（１回限り）。
