[ECU] Short circuit to positive -> What does it mean? Hello experts, I have sent my ECU to German for repair. When the ECU has been repaired and returned, I asked my Merc Specialist Mechanic to install the ECU. But there is an error sounds like this: "IFZ: Short circuit to positive" What does it mean? Does it mean the ECU is still faulty and not fully repaired? Or is it something else? Because of that error, the engine won't start, there is a response of the engine sound though, but the red and green LED on the rear mirror keep blinking. The car doesn't want to start. For your info, my car is W202 C-class year 95. Hope to get some advices and recommendation. Many thanks in advance...your help is highly appreciated. PS: I missed my car, almost 2 months not working..
