This guide will walk you through the process of performing a throttle relearn procedure on a 2024 Zongshen Aprilia APR250 motorcycle using the OBDSTAR MOTOMASTER diagnostic tool.
Tools Required:
Main Cable
OBDSTAR App (for reference)
Step-by-Step Procedure:
1. Locate the Diagnostic Port: On this motorcycle, the diagnostic socket is located in the front section of the bike. For quick reference to find the port and select the correct cable, you can use the OBDSTAR app.
2. Connect the Scanner: Connect the OBDSTAR MOTOMASTER scanner to the vehicle's diagnostic port using the main cable.
3. Power On and Select Menu: Turn the motorcycle's ignition key to the ON position. Then, on the scanner, navigate through the following menu:
Select [MOTO Diag] >> [CQZONGSHEN] >> [CQZONGSHEN V33.13] >> [Diagnosis] >> [zongshen-AOOILIA] >> [APR250]
4. Access Engine Functions: From the main menu for your model, choose [ENG] (Engine). It is good practice to first read any Diagnostic Trouble Codes (DTCs). In this case, no fault codes were stored.
5. Enter Special Functions:
Select [Special Function] and then [Agree].
Choose the [Diagn.throt.self-learn.] function.
Press OK to continue.
6. Perform the Relearn Procedure:
The scanner will now instruct you to turn the dashboard off. Wait for the communication with the control unit to end.
Then, turn the ignition key back to the ON position.
The scanner will confirm that the "Regulation [was] carried out," indicating a successful throttle relearn.
The procedure is now complete. You can disconnect the scanner and start the motorcycle to verify normal throttle operation.
