If out of range, replace the vehicle speed sensor.

Step 5: Reconnect Battery and Test Cruise Control

Reconnect the negative battery terminal.
Start the vehicle and engage the cruise control system.
Test the functionality at various speeds to ensure it operates correctly.

Step 6: Clear Diagnostic Codes

Use the OBD-II scan tool to clear any stored diagnostic trouble codes.
Test drive the vehicle to confirm that the cruise control is functioning properly and no new codes appear.
