| Defect | ① In the E13C engine control computer, due to an inappropriate control program for DPR regeneration, the urea SCR catalyst temperature may become higher than expected during DPR regeneration under high-speed, high-load conditions, accelerating catalyst degradation. Consequently, continued use may lead to nitrogen oxide emissions exceeding regulatory limits. |

| Remedy | ① For all vehicles, rewrite the engine control computer program to the improved specification. ① For all vehicles, inspect the catalyst according to our company's established standards, and replace the catalyst with a new one if it exceeds the standards. Additionally, remove the catalyst purification rate inspection, which was added as a provisional measure to the maintenance notebook's inspection and maintenance items. |
