It is a 2005 TF. I have removed the pektron SCU, no signs of damage to the PCB, also the relays look good. So I am going to send the unit to Paul technozen for diagnoses. In the meantime I would like to check the wiring harness, to see if the door lock wires indeed make contact with the pektron connector. I need a pektron connector pinout to do that. Looking at the test results it would surprise me if anything is broken in the wiring, but I want to rule out that part of the chain.
My idea of making a clone is useless to create a plug and play solution, because the key fobs are paired to a particular scu and cannot be paired to 2 scu's.
I would like to have a go at programming a pektron, therefore looking at a second hand pscan. I will put the request on the forum.
