Update: As I come across spare module boards, and have the time, I will add the relevant circuit diagrams of the boards to the site. The first is the AFT module or "Unit Lift-Roof" as its marked

Click the
Orange box in the wiring diagram below;

These are not likely to be of much help in finding faults, but might be handy in the future if any of the modules become scarce and do need repairing, however if the AFT module is anything to go by then as its 90% SMT, identifying / obtaining anything but the basic components will be a problem i.e. the 4 bit microprocessor with ROM code is never going to be sourced as a new item! The relay on the board however is still in production and is possibly something that could be easily repaired
Many thanks also to Ady (Northern Bongolow) for the loan of the above module
If anyone else has any spare modules / boards they want to loan (and if I have time) PM me, good candidates would be;
Sliding door Auto closure module
Sound Warning module
Climate Control module in the A/C
ECU and or TCU might be nice but likely to be time consuming due to there size, also differing versions in each vehicle type
the SRS and ABS boards have safety issues involved so probably best not to get involved with these!
