Rover 5AS remote programming t300+

[ruffles1986]

Hi mates. I try to program remote in rover 25, SCU 5AS system, i have t300+, but i can't comunicate with 5AS unit.
I see there is a cable for Rover to comunicate with 5AS or MEMS (ecu). Any have pinout to do this cable? I can comunicate with MEMS throug pin 2 of T300 to pin 7 (K-line), but i can't comunicate with SCU unit.

Thanks in advance.

Better buy cable not expensive and made in UK.

What year of that Rover 25?

Here the diagram to make your own cable.

From 2000 year

First time I hear about such cable. If car have OBD2 socket then SBB should do it - I never failed.

Cable has been around for several years
A company called techtronics in UK made them and there is a big write up on this forum plus Internet about it never used sbb myself but if works as you said cheap tool to use.

I try with t300+ and diagram for rover and doesn't work, i thinks is problem of the crap of machine, i buy only for this car and dont work.... Theres is a way to read code of remote? then maybe i can add to 5as module directly as Pektron system

then maybe i can add to 5as module directly as Pektron system

So this is pektron or what?

This is a 5as system. For pektron i have solution by eeprom.
And for 5as if i can read code from remote maybe can add directly to module 5as.

Hmmmm very old 3 pin cable existed.
Also i heard odd ground missing on OBD connector.

But i think i know what u mean.,,,

Separate rx n tx Comms on OBD pin 1 and 3 from memory and indeed separate OBD lead also exists. Recall writing software for it
I have it - but sadly my original AD100 burned years ago and these clones aren't the same.

PS. Don't rule out issue with car as most down scrap yard

SBB Clone work, solved!

I told you

That's why I completely do not understand idea of that 'special' cable...

AD100 doesn't have a built in multiplexer for that purpose. That's all.
