"it's really easy to short out the Serial pins and read the Aircon and other modules on that circuit"
But how? Assume I want to read pins 2 & 10, what pins do I connect them to on the scanner?
And do I actually 'Short' any pins on my car i.e. connect them to each other or to ground? - rather than connecting them to pins on the scanner?

So I bought the CR Pro, which does lots of makes of cars. I did that because we have cars by 3 other makes in the family as well.
The software for each marque is identical between the Pro (many marques) and single marque models like the LR.
In my early (serial no. just under 3000) car I got the following results -
It will read and clear-
Engine Control
Trans Control
Instrument cluster
ABS module
It will read but NOT clear
Driver's door
Passenger door Passenger seat
Body control module.
It will NOT read OR clear
Airbags/SRS – this is on OBD Pin 3 on these early cars.
Driver's seat
Security locking module. Aircon - Serial data - pins 7 & 15

Thanks. I'll need to keep looking. This breakout box discussion is interesting, maybe that will do what I need. Originally Posted by JohnNZ

So, this was interesting to me too, to be able to read the codes but no one wanted to expand.
Its raining so i had time to kill today and found this:
Hi Throwback, I recently had a similar problem trying to read the Air Conditioning Control Module with my Foxwell scanner. As I could get nothing out of it, I made the assumption that it was faulty and managed to get a new old stock module at a reasonable price. After swapping them over, I still had no communication. Further investigation and lots of forum searches revealed that on early OBD2 systems, there are issues reading the Serial Data Link Network modules, of which the Adaptive Damping Control Module is just one.
The solution is to short K (Pin 15 on the OBD2 connector) with O (pin7 on the same connector) while conducting the scan. As it's really difficult to do that on the data link connector with the scanner plugged in I invested in a cheap OBD2 breakout box (picture below).

Hope that helps

Thanks for that Dannio. I read it with interest and have noted it down for future reference.
At the moment my car has no obvious faults apart from the odd rattle, so I'm not inclined to start shorting out wires.
But I will try it if I need to access some of the modules I can't read at present, in the future........
