My car being a 2011 meriva, uses Tech 2 for diagnostics, it's not on GDS2 untill the 2014 model year, but not on the Tech2's onboard SPS list,  so i have to SPS from my netbook with GlobalTis 32b on it, using the Tech2 - J2534 passthru mode. 

But i've so far bought an IPC, a TIM and a PDC module (and a rain sensor.. but i know that's not vin matched) all were just removed from vehicles, not divorced, and when first connected they say 'mismatched vins'

But i just do a 'configure and set up'

My trailer interface module is playing up a little, some times it detects the plug insterted and will do the bulb out warning on the dash, sometimes it dosent detect the plug is insterted, 

i've 100% checked the switch in the socket is working, zero ohms when the plug is in, perfect connection when it's out (so the switch is open when plug is inserted) 

i can't talk to the TIM with the tech 2 as it says hardware mismatch or no software available... this is because my chassis number isnt on
