| MLIT filing number | 1122420 |
|---|---|
| Type | Statutory Recall (government-mandated recall) |
| Date filed | December 25, 2008 |
| Manufacturer(s) | Mitsubishi |
| Component | Wiring |
| Production period | May 2003 — November 30, 2008 |
| Vehicles affected | 96 units |
Defect
The harness of the engine coolant temperature sensor is routed and secured improperly, allowing engine vibration to cause internal wire strand breakage within the insulation. The resulting intermittent signal causes the air heater relay to cycle on and off repeatedly, leading to contact welding and abnormal overheating of the air heater. In the worst case, the air hose may be burned through.
Corrective action
On all vehicles, inspect the coolant temperature sensor harness. If a broken wire is found, replace the harness and air heater relay with new units. Extend the harness and secure it properly using an additional bracket, and install a thermal fuse on the air heater.

状況
エンジン水温センサのハーネスにおいて、固定方法が不適切なため、エンジンの振動等により素線が、被覆内で断線する場合がある。そのため、そのままの状態で使用を続けると、エアーヒータリレーがＯＮ－ＯＦＦを繰り返すことにより接点が溶着し、エアーヒータが異常加熱するため、最悪の場合、エアーホースが焼損するおそれがある。
改善措置
全車両、水温センサのハーネスを点検し、断線しているものはハーネスとエアーヒータリレーを新品に交換する。また、当該ハーネスを延長し、追加ステーを用いて適切に固定するとともに、エアーヒータに温度ヒューズを追加する。
