Hello all! We might have a problem with the ECU unit of this forklift truck,but we are not sure whether it is the ECU unit itself or rather the connector. The laptop does not seem to be able to properly communicate with the ECU.The ECU sees the laptop, but not the other way round. Can anyone advise how to check the connector or if the ECU is faulty, can anyone suggest a good company that repairs the ECU's in Europe? Many thanks!
