"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?

Hi,
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
Regards, John
