Overview
| MLIT filing number | 2104560 |
|---|---|
| Type | Improvement Campaign (manufacturer improvement measure / 改善対策) |
| Date filed | December 9, 2014 |
| Manufacturer(s) | Isuzu |
| Component | Airbag |
| Production period | October 2014 — November 24, 2014 |
| Vehicles affected | 1,938 units |
Issue
In the SRS control unit installed on light- and medium-duty trucks, the fault diagnosis control during engine start is incorrect. When the ignition is turned on, electrical noise may resonate with the output signal from the acceleration sensor. The SRS control unit interprets this resonance as an acceleration sensor fault, illuminating the warning lamp. As a result, the airbag may not deploy in a collision, compromising occupant protection.
Corrective action
On all vehicles, replace the SRS control unit with a corrected part.

状況
小型・中型トラックのＳＲＳコントロールユニットにおいて、エンジン始動時の故障診断の制御が不適切なため、イグニッションをオンにした際の電気ノイズと加速度センサの出力信号が共振することがある。そのため、ＳＲＳコントロールユニットが共振した信号を加速度センサの故障と判断して警告灯が点灯し、衝突時にエアバッグが展開せず、乗員保護性能が損なわれるおそれがある。
改善措置
全車両、ＳＲＳコントロールユニットを対策品に交換する。
