NOTE:

You can use a scan tool to (GDS) check if the battery voltage is proper before perform the "ASP CALIBRATION ".
Make sure that no connector engaged to the vehicle or scan tool is disconnected during the "ASP Calibration".
Once the "ASP Calibration" is complete, turn off the IG switch and wait for 10 seconds or more before starting the engine to check the operation.
