Description
The 22451 adjusts vehicle features through the factory steering-wheel controls without flashing performance tunes into the ECM. It supports the specified 2019–2022 GM 5.3L and 6.2L truck applications, excluding refreshed 2022 models: the twelfth VIN character must be 4 or lower.
Functions include throttle response, tire-size and gear-ratio calibration, TPMS thresholds, speed-limiter adjustment, auto start/stop control and DFM disable. A physical gear change can disable factory cruise control; this module does not restore it or correct resulting codes.
