BCM / Body / Gateway Tool
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.
OTOCHECKER is a mileage-verification tool unrelated to performance work; Softechpro Solutions focuses on ECU firmware editing for emissions/DTC modules and Stage tuning and does not read or alter odometer records.
