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
