Tool comparison
OTOCHECKER (commonly the OTOCHECKER 2.0 Mileage OBD unit) is a handheld device used to verify a vehicle's genuine mileage by reading the odometer values stored across the various control modules over the OBD port. Because many cars record mileage in several locations — instrument cluster, engine ECU, transmission, and other body modules — OTOCHECKER queries these modules and compares the values, helping used-car buyers, dealers, and inspectors detect odometer rollback. It supports a broad list of European makes where multi-module mileage storage is common. The tool is a checking/verification device rather than a programmer; it exposes discrepancies but does not alter stored data. It connects directly to the diagnostic connector and displays readings on its own screen.
A Fiat Body Computer Tool works with the body computer / BCM used across Fiat, Alfa Romeo, Lancia and related group vehicles, which controls the immobilizer, lighting, central locking and comfort functions and often stores the proxi/configuration alignment. It reads and writes the module to program keys, run immo/PIN operations, perform proxi alignment after a component swap, virginize or clone the body computer, and adapt a replacement so it pairs with the engine ECU and dashboard. Work is done over OBD or on the bench depending on the module. Users are Fiat-focused auto locksmiths and body-electronics repairers handling lost keys, failed modules and proxi mismatches. Because the body computer and its proxi configuration link the vehicle's modules, correct alignment is required for keys to be accepted and warning lights to clear.
