What Causes Engine Control System Failure?
1 Answers
This fault indicates that the vehicle's ECU is damaged. The ECU is the engine control computer, and the owner needs to check if the related fuses are damaged. If the fuses are all intact, the vehicle should be towed to a repair shop to diagnose the cause of ECU failure and replace it. Common causes of ECU damage include: 1. Water ingress into the ECU causing burnout. During rainy weather, some drivers may have to pass through waterlogged areas due to road conditions, which can lead to ECU short-circuiting and eventual burnout. 2. Failure of the ECU memory storage, similar to a computer hard drive failure, rendering the ECU inoperable. 3. Malfunction of the ECU's microprocessor, analogous to a computer CPU failure. When the ECU fails, the vehicle's engine cannot operate normally, necessitating ECU replacement.
