    Question Tech2/Central Locking help!

    Hi Guys

    A few posts ago I explained how my remote central locking just stopped working (coincidently after replacing the batteries), but even after al the syncing methods, nothing worked. I decided to take it to a dealer for a quick look, he plugged in the Tech 2, and it picked up the keys' signal, but when he tried to reset the system it kept saying that the ignition needs to be on, but it was (if you know what I mean) and I think this is also why I cannot sync the keys, cause the car's management does not see the ignition as 'on'.

    Any ideas on what I can do? The guy at the dealer told me to check all the wiring, but nothing has changed, why will it just one day give problems?

    Cheers mates!

    Does your car have the factory fitted alarm or not?

    I can give you pin numbers/ fuses to check with a multimeter but there are different on cars with/ without a alarm

    Yeah, it is the standard factory fitted alarm and central locking. I will be going through all my fuses one by one tomorrow, but any help will be great!

    Just for some info, the alarm went off when I unlocked the car, just before the central locking stopped working, and now I see that my rear brake lights are also dead.So my fuses do have some issues.

    Cheers!

    Ok another update, I just opened the cover over the ECU, but all the wires seem fine, still original. So I donb't know what the thing is with the Remote Central Locking.

    I also checked out the brake lights, the fuse is 100%, but no power seem to be going to the brake lights!!!

    Can anyone please help, I'm going on holiday in 2 weeks, and need to get this fixed.

    Thanks a million!!

    Lets start with the brake lights. If all the fuses and bulbs are ok the chances are it's the switch. Get under the dash with a multimeter and check it's got a live in.

    As for the central locking check fuses 13 and 21, these are ignition live fuses for the unit. If they are ok then you need to check pin 4 which is a black wire and pin 3 which is a red wire in the connector with the thinner wires in, this will be ignition live and accessory live

    If all of this is ok then it's probably a faulty central locking unit but get it tested properally before you comit to buying one

    Thanks I'll going to check the switch now, regarding the pins, where are they, and where do they go?

    Cheers Autosparks!

    Ok here is some good news!
    After testing the brake circuit and switch all tested fine, I then opened the brake light switch and started messing with the tension of the spring and the length of the pin, and now it works 100% YEAH!!!

    So now it is just the Central Locking still stuffed.

    Thanks!

    They go into the central locking unit in the drivers kick panel, below the bonnet release. South African cars are right hand drive too?

    Yeah, right hand drive too. I had a look there (but just at the wires, I didn't want to open the box). I only have one box there (I thought it was the ECU), is that the one? There are 2 sets of wire going into the box, so I should check the smaller of the two, correct?

    Yep thats the central locking unit also known as the bdy control module. Smaller of the plugs yes. I wouldn't open it up though
