|---|---|
| Type | Statutory Recall (government-mandated recall) |
| Date filed | April 6, 2010 |

| Vehicles affected | 215 units |
Filing in context
The Pressure control/transmission unit is the most frequently cited component category in this archive, appearing in 14 of its 4,890 filings. This filing is one of 31 Mitsubishi notifications from 2010 in this archive. For scale, 3,528 of the 4,890 filings in this archive report a larger number of affected vehicles; the vehicles involved here were manufactured over a span of about 13 years and 6 months.
Defect
The material and dimensions of the valve inside the ASR (Anti-Spin Regulator) valve — fitted to prevent drive-wheel spin — are incorrect. Air pressure acting on the back of the valve causes age-related deterioration and deformation under high-temperature conditions, which can block the exhaust port. Residual pressure then builds up in the brake lines, keeping the brakes continuously applied and causing the brake drums to overheat. In the worst case, this may result in a vehicle fire.
Corrective action
On all vehicles, confirm whether an ASR valve is installed. If present, replace the valve with the corrected part and replace the line connector with a new one. Additionally, add a notation to the maintenance booklet indicating that the ASR valve is a periodic replacement part required every 10 years.

状況
駆動輪の空転を防止するために装着されているＡＳＲ（アンチスピンレギュレータ）バルブ内部の弁の材質および寸法が不適切なため、当該弁の背面にかかるエア圧による経年劣化および高温環境下での変形により、排気ポートを塞ぐものがある。 そのため、ブレーキ配管内に圧力が残留し、常にブレーキが作動した状態となってブレーキドラムが過熱して、最悪の場合、火災に至るおそれがある。
改善措置
全車両、ＡＳＲバルブが装着されているかを確認し、装着されていた場合は当該バルブを対策品と交換すると共に配管コネクタを新品と交換する。また、ＡＳＲバルブが１０年毎の定期交換部品になった旨を、メンテナンスノートに追記する。
