Renault Kangoo 2007 1.6 16V - The immo indicator is on, the engine cannot be sta

  • Level 28  
    Hello, from time to time, lately more and more often, after switching on the ignition the immo indicator does not go out and the engine cannot be started - the starter turns. After switching the ignition on several times, the indicator goes out and we can enjoy the ride.
    Where to look for the reason, because one day it won't fire at all.
    For advising everyone and everything - the indicator light is not flashing but is lit continuously and 1.6 16V is a gasoline engine.
    Everyone says the topic is familiar and typical for Renault, but probably not entirely.
    The topic has been going on for a year and it's time to solve it.
    Installation reviewed, clean and dry. Mass points' OK. EAR nice, dry, nothing suspicious.
    I am asking for specific advice.

    Replace the ECU power control relay.

    Do you mean the H relay in the engine compartment - small - the designation in diagrams 238 - described as the injection block relay?
  • Level 34  
    Yes . This one I mean. To check, simply pull it out and see if the LED is constantly lit. And the fuel pump will not talk.
  • Level 28  
    OK, I'll check back tomorrow and let you know.

    -> genek1000 Thank you very much for the advice. It is a pity that this is not it.
    I checked, after removing this relay, the fuel pump is working and the immo indicator goes out.
    So you have to look further.
    Maybe someone has already solved a similar problem?

    Are we talking about the same relay J in this version of the box

    First, try to make diagnostics, everything will be clear. Probably the reader for repair. If you touch it, there is a chance that you will not start the car without replacing or repairing it.

    Yes, relay J, I have the second version of the box - the lower drawing.

    I was twice, made CLIP, there are no errors, admittedly there was no fault at the time of diagnosis - it does not occur on demand, only when it wants, more often.

    What reader are you talking about - it's just a key and a coil around the ignition.
    I have two keys, I recognize them correctly. The immo indicator lights up continuously and does not flash as if the key was not recognized correctly. I suspect a communication error between the engine ECU and UCH, cables and connectors checked, clean, dry

    No exchange, just what?
    I have touched it for a long time and I have a little idea about it, I would like to fix it before it fires permanently.
    I am thinking about replacing the ECU and UCH, but I am not sure it will help.

    Because it probably won't help if you take a good look, you have a ring on the ignition switch, there is also electronics inside. The ring is connected to this electronics, not to the UCH directly. No communication with the ECU, it is also flashing and not lighting the indicator. Anyway, see yourself by unplugging the plugs from the ECU and then from the ring.

    There may be inactive errors, a preview of the parameters at the time of the fault would say everything.

    Hello,

    I rode for two weeks without a problem. Yesterday the problem returned again. I couldn't fire it for an hour, then it fired and it's good again.

    The problem with connecting under CLIP is that the fault appears suddenly and suddenly, without reason, disappears. It is hard to leave him in the workshop for two weeks - "maybe he will catch him at that time".

    On one of the forums I found a description of how immo works at RENAULT - this is a fragment of Kangoo documentation available on the internet:
    Renault Kangoo 2007 1.6 16V - The immo indicator is on, the engine cannot be sta

    That would mean that:

    1 / engine computer does not correctly recognize the code given from the immo - that is, a problem in the electrical system (poor contact, damaged wire, etc.), or any interference makes reading difficult.
    2 / engine computer has a problem reading the reference code from its memory for comparison with the immo code.

    I looked through the electrical installation quite carefully, I see no problem here. I also try to limit possible sources of interference - blower, LED daytime running lights, chargers, etc. and I don't see the difference.

    In the second case, it would only be necessary to replace the engine computer.

    It is puzzling that the fault appears and disappears, for no apparent reason, which would speak for a problem in the electrical installation, unless it is a hardware problem of the engine computer.

    I think I will bring CLIP with me. I wonder if DDT 2000 could read the errors from the immo and the engine cassette at the time of the fault?

    Well, unless someone else has an idea?

    Clip should read the error even if the fault does not occur. It should be in remembered or sporadic errors. Only UNLESS after a dozen or so starts will disappear.

    is a very laconic answer, could you develop it somehow? Be more generous in the details, try to show that you are right, and not just offend others.

    If the fault remains in the fault history, it will not be erased even after the car has been fired 100 times. The last time I had a similar fault in the SC 1 lift, only that after the immo indicator was lit, the orange rectangle indicating the electronic fault was still fired. A loop near the ignition switch and exactly one cable was in some strange way broken off.

    There was a similar problem in my Kangaroo, and I got rid of it by jumpering the plugs from the shock sensor. As he took his hand.
    best regards

    The shock sensor has nothing to do with this fault, it was mentioned above.
