    ECU Fault Codes

    DISCLAIMER: The information in these documents are a collection from experience (friends or myself), magazine articles, mailing lists and Internet web sites etc. So don't take these as 100% correct gospel, hence I don't take any responsibility for any of these guides.


    Fault codes are recognized problems or faulty sensors to the EMU (Engine Management Unit) which is a ECU (Electronic Control Unit). The ECU relies on the sensors on your car to make it run at it's optimum performance at all times. When a sensors goes wrong or there is a fault with the engine, the ECU sees this problem and logs the fault code within it's memory (NOTE: not ALL problems are logged, depends on what system your car has). Often the ECU warning light on the dash board may light up, indicating to you that there is a problem.


    Do all ECU's handle fault codes?


    If your engine is fuel injected then it needs a ECU to control the injection timing. All Vauxhall models that have injection need a ECU to do this and hence they will have the facility to log fault codes. If your engine is run on a carburetor, then it has no ECU, hence no fault codes can be logged or read.


    How do I read the fault codes?


    There are two common ways to do this. The first is to use a TECH1 reader which is an expensive bit of equipment. Some dealerships could charge you £50 just to connect it up to your car. The second option is FREE and YOU can do it....with a paper clip.


    The paper clip method flashes the ECU warning lamp on the dash, and you read the amount of flashes and pauses. The chart supplied in this article tells you what the fault code means. The paper clip is used to short out two pins in the ALDL connector (also know as 'diagnostics plug' or 'test connector'). These are commonly coloured blue and is located in the engine bay. Some newer models (i.e. Eco-tec engines) have the test connector inside the cabin.


    General Notes:

    Just before you start, make sure you note the following:


    If you don't have one, buy a Haynes manual for your car and have this is front of you if you find a fault and wish to investigate it.
    You'll need a paper clip and a pencil and paper to jot down the fault codes as they are flashed up.
    You do not need to start the engine but it dosn't hurt. Just switching on the electric's is enough (i.e. dash lights come on).
    If the paper clip is inserted in the wrong 2 pins, don't worry you won't damage nothing. All that will happen is the fault codes will not be displayed.
    OK, got all the above? Then follow the steps below (remember to click on the pics for a bigger view):


    Step 1 Step 2 Step 3

    Open up the bonnet and look inthe engine bay for a 10-pin blue connector with a blanking plug or plate. Disconnect it from the blanking plug. With the connector pointing towards you and the retaining clip at the bottom, short the top two pins (A & B) on the left-hand side with the paper clip. Get in the car and switch on the electric's. The ECU light will begin to flash and pause a number of times, take note of these.


    Once the wire link is in place and the electric's are on, the ECU warning lamp will begin to flash out the codes (wait for the initial boot up check that lights up all the warning lamps). Each fault code is repeated 3 times and then it moves onto the next one (if any). Once at the end of the logged fault code list, it will go to the beginning again, giving you plenty of time to note down the code (on each fault code shown, there will be a pause before it shows the next one). It will carry on like this for ever until you remove the key from the ignition. To clear the codes simply remove the battery leads (for Simtec ECU's fitted to Eco-tec engines, start the ignition 25 times to clear the codes).


    For example, lets say there was a ECU warning lamp noted and the owner wanted to read what fault code was logged. The owner has already put the wire link in place and switched on the ignition. A flash is indicated by an astrix (*) and a pause is shown as a dash (-).


    *-** (1 flash, a pause and another 2 flashes = code 12)
    *-** (12)
    *-** (12)


    **-*** (23)
    **-*** (23)
    **-*** (23)


    *-** (12)
    *-** (12)
    *-** (12)


    *-** (12)
    *-** (12)
    *-** (12)


    Owner then takes the key out of the ignition.


    Lets go through what has happened. After switching on the ignition, the dash board lights up showing the self check, after that all the lights go out and the ECU warning light begins to flash the error code. The first code is 12 (one flash, a pause and then two flashes). This is repeated 3 times.


    Code 12 at this moment means initiation of diagnosis. After that came code 23, which means 'Knock control module', i.e. there is most likely a faulty unit or a bad connection at its plug. After code 23 has been repeated 3 times it goes onto the next fault code (if any).


    Before it does, it flashes a separator code which is code 12 (NOTE: on later models, ie Simtec, the separator code is 10 and not 12). It flashes this 3 times before going to the next fault code. The next code is code 12 again which means its finished showing the logged fault codes and has started back at the beginning. The owner can switch off the ignition. A healthy car should display a stream of code 12's (note: some ECU systems will also show code 31 (or 0335 for Simtec) because it doesn't see the engine turning over, this is not a fault because you haven't started the car).


    Fault Code Chart:

    Over the years there have been many different models in the Vauxhall range and hence there are different ECU systems. With each different system there are (usually) different fault codes. Listed below are the fault codes, search for the model of your car and click on the link to view the fault codes.


    This list is by no means complete and still need gaps filling in and some corrections. If you know more about other engine systems or can correct anything below, please e-mail us at ecu_codes@topbuzz.co.uk. Thank you.

    will ja nix sagen aber hier fehlt einer undzwar der 2,0 8v c20ne 4x4 wie ich ihn hab

    Hat jemand zufälliger weise ne liste der FC von der Motronic 2.8 in deutsch ???
    Oder sind das alle die in den "So wirds gemacht Büchern stehen " ???

    @armani
    gehts hier nur um fehlercodes die mit dem motor zusammenhängen und nicht mit allradgetriebe.
    denn der motor im 4x4 ist ja der gleiche wie im frontriebler
