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.

Before clearing
Can the code be cleared?
Clearing a code without fixing the cause removes useful evidence and may only switch the warning off temporarily. Save the full scan first; a permanent or repeatedly returning code needs testing.
Confirm the suffix, reporting module, model, year, engine and live data before replacing a component.
