Filing in context
The Computer is the most frequently cited component category in this archive, appearing in 42 of its 4,890 filings. This filing is one of 33 Isuzu notifications from 2014 in this archive. For scale, 1,443 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 14 years and 1 month.
Defect
In trucks, the automated mechanical transmission control unit, CNG engine control unit, or trailer information control unit is mounted beneath the instrument panel, directly below a heater through which coolant (antifreeze) circulates. If coolant maintenance (replacement) is neglected, rust develops in the cooling circuit, causing the heater core to crack and coolant to leak and drip onto the control units below. Continued operation allows coolant to penetrate the control unit interior, creating a short circuit in the control circuitry. This may illuminate warning lights and impair vehicle control or, in the worst case, result in a vehicle fire.
Corrective action
Owners will be notified of the requirement to replace coolant (antifreeze) on a regular two-year interval. On all vehicles, a waterproof cover will be added above the control units, and the control units will be inspected and replaced with new units if damage is found.

状況
トラックのインパネ下側に設置されている自動クラッチ付機械式変速機制御ユニット、ＣＮＧエンジン制御ユニットまたはトレーラ情報制御ユニットにおいて、上方に設置されているヒータ内を循環する冷却液（不凍液）のメンテナンス （交換）が不適切な場合、冷却回路に錆が発生することで、ヒータコアに亀裂が発生し、冷却液が漏れて制御ユニットに滴下することがある。そのため、そのまま使用を続けると、制御ユニット内部に冷却液が浸入し、制御回路の短絡により警告灯が点灯し、制御に支障を来し、または、火災に至るおそれがある。
改善措置
使用者に対し、冷却液（不凍液）の定期交換（２年毎）の必要性を周知し、全車両、制御ユニット上部に防水カバーを追加するとともに、制御ユニットを点検し、損傷している場合は新品と交換する。
