Matching method

Manual matching method: For the throttle matched by mechanical cable, the manual reset method is adopted, and the telephone switch is turned on and off for many times continuously, so that the vehicle computer can delete the original throttle memory and store new throttle data.

Power-off matching method: after replacing the throttle, disconnect the negative electrode of the battery for a few minutes, and the vehicle will enter a dormant state. During this process, the original memory of the on-board computer will be restored to the factory settings. But this method is only applicable to low-grade vehicles. Diagnostic instrument matching method: read the data with a special diagnostic instrument, and then follow the steps to reset the adaptive value to zero, clear the fault code, start the vehicle and run normally, indicating that the matching is successful.
