The R50/400SD TPMS software update for Bartec's 400SD TPMS tool adds the ability to program popular aftermarket sensor solutions from Alligator and Orange, in addition to the Schrader EZ-sensor. Programmable aftermarket sensors have been available for some time, but it was Bartec that first developed and created the process of using a TPMS ccan tool to program these sensors. The updated software contains additional OBD Relearn coverage for Ford and GM vehicles. It also adds TPMS OBD relearns for Volvo cars.
