Important Information

This service resets the immobilizer data only. Depending on the application, additional flashing, coding, configuration or synchronization may be required before the transmission will operate correctly.

An immobilizer reset does not make incompatible transmission hardware or software compatible. The transmission model, control unit, gear ratios, software and vehicle communication must be suitable for the intended application.

Remote service appointments require the vehicle or bench setup to be powered, connected and ready before the scheduled start time.
