![]() If only one side of the size bulbs does not light, check fuses Ef23 or Ef28. Įf11 (10 A) – Main relay circuit, engine control module (ECM). Įf10 (15 A) – electronic control unit (ECU), ignition coils, EGR valve. ![]() #Chevrolet lacetti ecu file windowsĮf9 (20 A) – power windows in the right front and rear doors. In the worst case, if there are problems with the temperature and pressure of the antifreeze, the cause may be a burnout of the cylinder head gasket.Įf8 (30 A) – high speed of the cooling fan (radiator). If the engine itself is running, check the antifreeze level, the coolant temperature sensor, the radiator cap and the expansion tank (the valve in the cap must work properly, the plug must be tight), the thermostat is in good condition. Check that the fan is working properly by applying voltage directly from the battery. If the fan does not turn on (it is rather difficult to determine its operation by sound, because it works quite quietly), check, in addition, fuses Ef8, Ef21 and relays K9, K11. Įf6 (20 A) – cooling system fan (radiator). ![]() It will work – most likely the contact on the body, the wire from the battery to the body of the car, has weakened.Įf5 (30 A) – ignition (circuits F1-F4, F9-F12, F17-F19). ![]() If it does not work, apply voltage to it with separate wires directly from the battery. This will check that the starter is working properly. Make sure that the battery is charged and its terminals are firmly fixed, put the gearshift lever in neutral and close the contacts on the retractor relay near the starter. If the starter does not turn, check also relay 4 on the bracket under the dashboard on the driver’s side. Įf4 (30 A) – ignition (starter, chains F5-F8). On the inside of the cover, the original fuse and relay diagram is applied.Įf1 (30 A) – Main battery (circuits F13-F16, F21-F24). #Chevrolet lacetti ecu file softwareDepending on the vehicle and ECU type the chip tuning process can take under an hour and if at any time you wish to return your vehicles ECU to its original default settings, this can be done easily and free of charge as we always keep a copy of the original software as a backup.Main fuse box is located on the left side, between the battery and the coolant expansion tank. The technician will then upload the original map to our map writing team who will adjust the parameters to maximise the performance, fuel economy or a clever blend of both. In some newer models the ECU will have to be removed from the vehicle and the casing opened, our technicians will then use specialist tools to read the original map straight from the processing chip. In many cases the map stored on the ECU’s processor can be accessed via the on-board diagnostics port (OBD) in the vehicle, normally found under the dashboard. We do not change any hardware in your vehicle, we just modify the operating parameters in the ECU’s program or ‘map’.
