Overview
| MLIT filing number | 1124660 |
|---|---|
| Type | Statutory Recall (government-mandated recall) |
| Date filed | February 9, 2010 |
| Manufacturer(s) | Lexus, Toyota |
| Component | ABS |
| Production period | April 20, 2009 — February 2010 |
| Vehicles affected | 223,068 units |
Defect
The ABS control program is calibrated incorrectly, causing braking force after an ABS activation cycle to fall below the level present immediately before activation. When ABS activates during braking on icy or uneven road surfaces, the driver may experience a pronounced sensation of free travel or delayed braking response. If the driver maintains constant pedal pressure after ABS deactivates, stopping distance may be greater than anticipated.
Corrective action
On all vehicles, reprogram the ABS control program with the corrected software. In the interim, notify owners of precautions to observe while driving prior to the software update. Note: For the Prius PHV, SAI, and Lexus HS250h, the control program will be updated as soon as the corrected software is available.

状況
ＡＢＳ（アンチロックブレーキシステム）の制御プログラムが不適切なため、ＡＢＳ作動完了後の制動力が作動直前の制動力より低下することがある。そのため、ブレーキをかけている途中に凍結や凹凸路面等を通過してＡＢＳが作動すると顕著な空走感や制動遅れを生じることがあり、そのまま一定の踏力でブレーキペダルを保持し続けた場合には運転者の予測より制動停止距離が伸びるおそれがある。
改善措置
全車両、当該制御プログラムを修正する。また、制御プログラム修正までの間の運転時の注意事項を、使用者に周知する。 なお、プリウスＰＨＶ）、ＳＡＩ、レクサスＨＳ２５０ｈの３車種については、対策プログラムが準備でき次第、当該制御プログラムを修正する。
