Check Engine light on? A scanner or other diagnostic tool can indicate the trouble code(s), which will quickly point you in the right direction. At Advance, we have hundreds of diagnostic tools, including Bluetooth-compatible scanners for wireless connectivity.
The advent of computerized engine controls in the 80s meant the Check Engine light (CEL) on the dash alerted drivers to potential problems. An illuminated CEL means that a sensor or a system on the engine has registered a reading that's out of normal operating spec, and the engine computer has stored a trouble code.
When the CEL is illuminated, a technician can attach a code reader tool to the vehicle's diagnostic port and read the trouble codes stored in the computer. This makes troubleshooting a lot easier than it was in the old days, when a mechanic might have to rely on educated guesses and intuition to nail down a problem. Shop with us to find scanners and code readers that can help you quickly troubleshoot a problem. Our selection ranges from basic code reader devices for your 90s car all the way to Bluetooth-enabled scanners for your state-of-the-art late-model car.
