Save the complete scan, confirm the full code and reporting module, then test using model-specific multi-brand technical information.
- Capture the evidenceSave the complete all-module scan, code suffixes and freeze-frame data.
- Prove the basicsTest battery condition, system voltage, power and grounds.
- Identify the reporterConfirm the module that logged the code and check circuit integrity.
- Compare live dataReview commanded and actual values under the conditions that set the code.
- Test before replacingUse model-specific wiring diagrams, pin tests and technical information.
- Verify the repairClear the code only after recording evidence, then confirm it does not return.
