Recently, I was looking around the 2021-up Chevrolet TrailBlazer's owner's manual online regarding Tire Pressure Monitoring System relearn procedure. Surprisingly, it's a Stationary relearn. Yet my Autel MaxiTPMS TS508's position relearn procedure is Copy by Activation and Copy by Manual Input.
The question is, if the 2021-up Chevrolet Trailblazer is capable of a stationary TPMS relearn as its Buick Encore GX counterpart, why didn't Autel take notice before issuing software updates? Given the only workaround to activate four sensors on the 2021-up TrailBlazer is using TPMS Diagnose instead of Position Relearn. Or select Scan All Sensors under Quick Mode.
