How to match Cadillac atsl cleaning throttle

There are three common methods of throttle matching: manual matching, power-off matching and diagnostic instrument matching. Generally, it is necessary to set the throttle to zero after replacing it with a new one or disassembling and cleaning it. The matching process is a computer self-learning process, which re-identifies the position and angle of the throttle.

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. Verify whether it is successful and whether the vehicle can run normally.

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. However, this method is only applicable to low-end models, and the test run can be normal.

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.
