NOTE: Apply one of the enclosed TMA-adhesive labels on the side of the ECM. Do not forget to enter the return into the Pans Volvo Vision core return screen (option 2, TMA testing returns) and enclose packing list.
For US, pack the ECM in a box, labelled with the second TMA-label, and send it to TMA, Rockleigh, for re-programming.
For Canada, the ECM should be handled the normal way, i.e. shipped to TMA, Toronto. This means that the second label from the kit shouldn't be used.
