A stored diagnostic trouble code or a related system warning.

Test, do not guess

Possible causes

The precise cause depends on the reporting module, vehicle specification, circuit condition and software level.

Evidence-led checks

Recommended diagnostic route

Save the complete scan and confirm the code against model-specific technical information before testing.

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.

A DTC is evidence, not a parts order.

Confirm the suffix, reporting module, model, year, engine and live data before replacing a component.
