Sorry, I don't know anything about the electronic magic that happens inside the box, so other than making sure the module has a good power supply and ground I don't know how to test or fix it. I've fitted a few of those cheap remote locking modules and to date I've never had one fail. If one of mine did fail though I'd just replace the box. I wouldn't even bother trying to repair something that is so cheap to replace.How to test and fix any transmitter or receiver on a remote locking module which is not working?
This thread has been running that long I can't remember what we did at the time it was installed. Do you know what post in the thread we were discussing this?Cutting power supply means.... whenever any door is open or when the key is inserted at the ignition lock....so that remote unit will not get power, that's how we wired the time it was installed....
There can't be anything wrong with the wiring on the car then, meaning the problem has to be inside the module.Took out the remote control unit from the car, and I retest the remote locking system independently by testing from a 12 v DC adapter external source power 220 v AC home.
Yes, same problems. Sometimes, it receives and sometimes not!!!!
What your asking for here is what is often called a switch back lamp. I think the circuit for this one will be a bit more complicated than what you've done before. But why reinvent the wheel when you can just buy a ready made switch back lamp on ebay/amazon. They aren't that expensive.Awaiting for the simplest circuit diagram...😇
