Description of Defect
Mitsubishi Diamante – Engine Speed Improvement with ECU Update
In the control computer of the prime mover (engine ECU), some air volume control programmes are inappropriate, so when power steering is operated during idling, etc., a load may be placed on the prime mover, causing it to temporarily slow down, and in the worst case, the prime mover may stop.
Improvement Details
Change the engine ECU programme to the countermeasure.
