Service function guideThrottle Body Adaptation

This guide delivers a complete, professional workshop procedure for performing a throttle body adaptation, the relearn process that restores idle stability and pedal response after cleaning or replacing an electronic throttle body. It is written for working mechanics and experienced DIYers who already understand basic engine management and have access to a scan tool with bidirectional controls. You will learn how the electronic throttle system operates, when an adaptation is mandatory, how to prepare the vehicle and equipment, and how to execute the full step-by-step relearn across common vehicle architectures. The guide also covers verification, platform-specific differences, common mistakes, troubleshooting failed adaptations, and essential aftercare so the repair holds up in service.
