    Hello, I am looking for an ecu installation diagram (pin output description) for astra g with 1.6 16v Z16XE 2004 engine.
    I have a problem with the main fan not working, errors no:

    P1482 - Fan relay 2
    P1483 - Fan relay 3
    P1530-A / C clutch relay



    I excluded the errors of the relays located in the longitudinal relay box, right next to the battery, because the relays are functional and shorting them causes the fan to be switched on manually.
    I also learned from numerous forums that the operation of the fan in this model is already controlled by the ECU.
    So I'm going to first check if there is a break in the installation from the ECU to the relays, and if there is no, then you have to look for errors in the ECU itself.
    The problem is that I can't find the right pin diagram in the plug for my aster, is there anyone able to rescue me ??

    From the site:
    http://codecard.eu/carprog/software/opel-logi...5-5-siemens-simtec71-simtec71-1-delco-diesel- delco-multec- / prod_129.html
    I found out that my driver is Delco Multec with markings on the M and K driver.
    Somewhere on the forum I found such a diagram, but it probably does not apply to my engine, because there are plugs A and B there, if this is the diagram, please correct me and tell me which plug is which, I attach the diagram in the attachment.

    If any of you have the correct diagram for this car, please send it
    Thanks in advance for your help
    Greetings, Piotrek

    That should help you a little. Connector M, in your diagram A is all about the engine (sensors, injectors, ignition coils), connector K, in your diagram B is the rest of the car (odometer, relays).
    On page 21 of the diagrams you have the Z16XE engine, in cars with air-conditioning the fans are controlled by an additional module described on page 35, where you also have an option diagram without air conditioning.
    In these drivers, they like to break the internal connections between the board and the connector, difficult to repair, but with a little practice it can be mastered.

    I haven't hit this hybrid with fan errors yet, usually it's immo, charging (generally damaged communication), shaft sensor or EGR,

    But the colleague above suggests the driver to the table very well, open it and check the connections between the print and plugs.

    If there is air conditioning, it should just be a separate module from the fan control and compressor clutch and maybe it is failing.

    Hmm, in general, I don't have communication with ECU either, because I can't go into it and do any test, maybe because it's not optech, but in my friend's chest
    It normally went in and did the relays test, etc.
    It will eliminate for now that the installation has collapsed somewhere, which I doubt, and then I will look at these wires.

    Do you know where this module is? Because I was convinced that everything comes from the ECU. The fan control module, which was once under the wheel arch, is definitely no longer present in this model, because I looked there.
    Thanks for showing interest

    How did you diagnose errors? Because if you were able to read them then communication is there.
    The module should be on the front left, what you have this air conditioning because it may have been in cars with automatic air conditioning.

    I have a manual air conditioning, I do not have this relay in the box, I only have 2 relays in the box.
    I have looked after this module too and it is not there.
    I diagnosed with the usual programs:
    * OPUS CARS CTMem
    * Autocom

    Since 2003, there is no fan module.

    Ok that's great, so I'm going to rummage in the ECU :D

    1st thank you for this thread! It helped me to fix my ecu (Delphi Delco HSFI 2.1 for Astra G 2002 1.6 Z16XE).

    While doing it, I made this document to help my troubleshooting.
    It is based on material above and may contain errors, but if you can read it you know how careful you need to be. :)
