AUTO / KNOWLEDGE
Real-world use cases
AutoCodes supports everyday decisions: understanding a warning light, preparing a workshop visit or checking official used-car information.
Used car
Before you buy
Decode the VIN for declared basic data and search general campaigns by year, make and model. Then confirm the exact VIN with NHTSA or the manufacturer.
On the road
A light just came on
Tell apart a warning that allows careful travel to a workshop from a red signal that requires a safe stop.
At the workshop
Arrive with better questions
Print the meaning, possible causes and observed context. Do not demand a particular part based on one code alone.
Maintenance
Do not erase clues
Before clearing codes, save freeze-frame data and check related codes. Clearing memory does not repair the cause.
