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.
