So, this started to become hopeful, with Vega offering to take a look and TheBoy finding a second unit...
And now silence, so back to square 1?

I guess I'll have to start going through breakers.

[TheBoy]

Sorry prj, been busy with friends all long weekend (Monday was a UK holiday), will try to find the security code for the unit I have, but may take me a day or 2 (if you saw my garage, you'd understand )

Be patience, just ordered a new programmer, it will arrive within a few days.

Ok, cool.
Thanks for helping out guys

[TheBoy]

I found the code

Where does the ECU need to go prj?  If you don't need any more, no problem, there is another member about 50 miles away that could do with one for testing a problem he has...

I'll take it!
I messaged you with my details.

Thank you!

I'll get it sent off in the week when I can get to postoffice

Very good, one step closer to solving this.
I'll read the EEPROM off of the unit you send me, and compare as well.

Whether I find where the code is or not, I will still be able to fit the unit you send me to the car and get everything to work

So I connected the diagnostics again.
Basically the first row of characters in the dump is exactly what is shown in the diagnostics as ECU ID, except it's read 2 bytes at a time, and the high and low byte are swapped.

So we can pretty much rule out any of that being the code, it goes like ES,2442,6916,1200,4700.
Also, it can not address individual bytes, rather it has to always read two bytes at a time, as it is a 16 bit memory.

So if we assume it is an integer and the integer is between 1000 and 9999, and it is stored exactly the same as the string data (the high byte and low byte are swapped), then looking through the dump, we get the following possible numbers:
3855, 2560, 5140, 2590, 1124, 1310, 2077, 4313, 7423, 4096, 4401

I wish I had an emulator for that 93LC chip. I could just see where it stores it's countdown timer and bruteforce it.
Ah well.

prj - just to confirm, it is this bit?



Note that the ident may be different, but I think that as long as yours is a facelift saloon, this should work (although you'll have the usual early facelift problem of key out of ignition to open boot).

Yup, it's this one.

Yea, I have that problem anyway.
But doesn't matter, I think I can open the boot with the key I have, once I get it paired (I got a 3 button spare).
The biggest ball ache really is not having to take the key out of ignition, but the fact that if I want to put something in the boot I have to first get to the car, get in, then press the boot release button, then get out again, because my remote doesn't work :/

You will need the YP ident, than its possible to open the boot with the key in, just hold the boot release button for 3 seconds.
Or modify it with a TIS solution.

Not too bothered about it tbh, more important to get the remotes working
Did you get anywhere with reading the dump?

No did not receive the programmer yet.

I have an LT ident and don't have to take the key out to open the boot. Or didn't. My unit packed in a month or so back. Now the central locking, courtesy light and boot button have stopped (although boot still opens on key fob.) Oddly enough I tried an SW board in mine (straight swap) and it didn't work at all. Put the original board back in and took the SW board back to the scrappy. TheBoy tried to read my board with the tech2. Nada.

I'll be following this thread with interest to see if I can fix mine afterwards!
