BMW OBD-2 service resetter lead break
 

Getting ready for my car's next service, I found my service resetter 'tool' , as above, red green and yellow buttons with a Clock, Insp and Oil lights had been disconnected from the cable. Inside, all that held the main cable was a blob of high melt plastic, which had become detached, hence the separation.

Does anyone know which wire goes where on the PCB. I can see where the three tiny leads go Red, Black,and white or pink?
On the PCB the connections are identified as 'UBAT', 'GND' and 'K-LINE'. Once having the correct matchings, I can easily do the soldering.

Whilst I am reasonably adept at using the paperclip method, I prefer something a little safer.

Thanks in advance for any help,

Well - What a disappointment. 101 viewings and not one reply.

Does no one on the forum know which lead goes where??

I had a BMW resetter years ago but I'm not conversant with the internal wiring. I suspect few here will be. I thought it was a bit big and clumsy for what it does and sold it. I got one of those OBD plug type with a push button. In your position, I think I'd buy a new tool, they can still be had for around a tenner.

Just taken mine to pieces,

.
K-line = Yellow
UBAT = Red
GND = Black

I am not sure what you are asking but if it is any help Red is a permanent live Black is earth and the white/pink is the K line.

Hello dattrike and tonytolle,

Thank you both for your replies. They both confirm what I thought, but I just wanted some confirmation.

Geoff.
