Omega Electrical and Audio Help / Re: Central locking inoperative using key fob.
« on: 02 April 2024, 23:58:56 »
Well, I had both keys from the problem car checked in front of my own eyes - both keys transmitted a signal from all 3 buttons.
Which led me to think that the original ECU may have actually been affected by water ingress (possibly?). Perhaps a gluten for punishment, but I decided to throughly but gently clean all the contacts for the connector block on the 'problem' ecu. Refitted it, and hey presto, the c/locking worked with both original keys as did the boot release. Tried it umpteen times and all was well. Even the interior light behaved itself and went out as it should
Cracked it I thought. Although the c/l was working ok, unfortunately, the interior light issue came back and refused to go out, and then the alarm decided to keep going off, and even disconnecting the battery within the 15 secs after switching the ignition off, refused to silence it. After approx an hour of alarm activations, it just stopped, but the interior light refused to go out. It eventually did after about a further hour, but after another 15 mins or so came back on without me even going near it It the went out again and as I write this is stil out....
I think the next thing is to put the c/l ecu from the donor car back in, and see if the interior light and alarm gremlins come back. If not, then the original ECU must be faulty - surely (?) - if they continue, I'll have to look elsewhere.....but where?
I was just curious really when the keys found to be working ok, whether the original ecu would work too.....
To be continued..
