All repairs include inspecting upper and lower PC Board for defective components and/or traces. We replace components only with the latest revision from the Original Equipment Manufacturer that are substantially more reliable than the original versions. The entire TIPM will be cleaned and the external relays and fuses will be tested. TIPMs are then bench-tested, and QA tested in a live vehicle prior to shipment. The repair is warranted for 1 year from the date of repair.
