Filing in context

Defect
Issue 1: The vehicle stability control (VSC) system software is incorrect. If the VSC function is switched off and the system is then shut down with the brake pedal held, VSC does not return to the on state upon restart. The VSC-off indicator lamp remains illuminated and VSC may not operate. Issue 2: On the body near the shock absorber mounting area inside the engine compartment, incorrect welding equipment settings resulted in some vehicles leaving the manufacturing process without the required weld being applied. Continued use may cause cracking at that location and, in the worst case, may impair driving stability.
Corrective action
Issue 1: On all vehicles, reprogram the brake actuator control computer with the corrected software. Issue 2: On all vehicles, inspect the shock absorber mounting area for the presence of the required weld. If the weld is absent, apply the weld. If damage is found at that location, perform the necessary repairs.

状況
①横滑り防止装置（ＶＳＣ）において、制御プログラムが不適切なため、ＶＳＣ機能オフ状態でブレーキペダルを踏んだままシステム停止後に再始動すると、機能オン状態に復帰しない。そのため、オフ表示灯が点灯し、ＶＳＣが作動しないおそれがある。 ②エンジンルーム内のショックアブソーバ取付部付近のボデーにおいて、溶接設備の設定が不適切なため、当該部位に溶接が行われていないものがある。そのため、そのままの状態で使用を続けると亀裂が生じ、最悪の場合、走行安定性を損なうおそれがある。
改善措置
①全車両、ブレーキアクチュエータ用制御コンピュータのプログラムを対策仕様に修正する。 ②全車両、ショックアブソーバ取付部付近の溶接有無を点検し、ない場合は溶接する。また、当該部位に損傷が認められた場合は、補修を行う。
