Signs Your Vehicle Needs a Diagnostic Scan

Modern vehicles monitor hundreds of parameters and will alert you when something is outside normal range. Here are the most common triggers:

Check engine light is on

The check engine light (MIL) indicates the engine management system has detected a fault. It can relate to emissions, sensors, fuel systems, or many other components — a scan is the only way to know for certain.

ABS, airbag, or traction control warning lights

Safety system warning lights should never be ignored. These systems are critical to your vehicle's safety performance and any fault codes should be read and addressed promptly.

Intermittent faults that are hard to reproduce

Some faults only occur under specific conditions. Live data monitoring during a diagnostic scan can capture what's happening in real time, even when the fault isn't immediately obvious.

Poor performance after a repair

If your vehicle isn't running as expected after a repair or parts replacement, a diagnostic scan can confirm whether the fault has been resolved and whether any codes remain stored.
