What are the symptoms of a faulty ECU in a Chery A3?

[GageFitz]

Chery A3 ECU failure symptoms are as follows: Engine warning light stays on: If other engine hardware checks show no issues but the warning light remains illuminated, the ECU may be faulty. Difficulty starting the vehicle: During startup, the vehicle's ECU automatically increases fuel injection. A damaged ECU may result in insufficient air-fuel mixture concentration, making the vehicle hard to start. Internal program malfunction: Fuel injection quantity, ignition timing, transmission shift logic, and other functions may be affected. If the vehicle exhibits poor performance or fails to ignite, the ECU should be inspected for potential damage.
