Fault Codes & Warnings
Fault codes are error messages stored in your car’s ECU when something isn’t working properly. They help identify issues with the engine, fuel system, emissions, ignition, or electrical circuits.
The check engine light can indicate many problems—from minor issues like a loose gas cap to serious engine faults. A diagnostic check reads the fault codes to pinpoint the exact cause.
Yes, fault codes can be erased temporarily, but if the underlying issue isn’t fixed, the code and warning light will likely return.
No, some codes are warnings that don’t affect driving, while others signal urgent problems needing immediate attention. Our diagnostics help prioritize what to fix first.
Using specialized diagnostic tools, we connect to your car’s ECU, retrieve fault codes, and analyze live data to understand the issue and suggest solutions.
While it doesn’t predict everything, diagnostics can detect early warning signs and hidden faults, helping prevent breakdowns before they happen.
Safely pull over if possible, and avoid heavy engine use. Contact us to schedule a diagnostic check as soon as you can.
