Check Engine Light Codes
It’s FAST and EASY… if the Check Engine Light is on in your vehicle, schedule a time with us so that we may retrieve the diagnostic trouble codes from your car. Knowing what issue is causing the check engine light allows you to determine if an immediate repair is necessary or you can wait to plan any repairs around your next state emissions test. Schedule today so that one of our expert ASE technicians can retrieve any CEL codes from your vehicle’s memory or call 410-828-5750.
Diagnostic Trouble Codes
The Check Engine Light (CEL) can illuminate for hundreds of different reasons. While some issues that trigger a diagnostic trouble code (DTC) require immediate attention, most are for emissions related symptoms and are not necessarily critical to the safe function of your vehicle. It is best that you not wait to determine what type of code is the reason the check engine light is illuminated.
- Powertrain ‘P’ codes
- Communication ‘C’ codes
- Network ‘U’ codes
Maintenance service Codes
More automobile manufacturers are starting to incorporate maintenance codes into the vehicle’s driver information center. The maintenance required light is not the same as the vehicle’s check engine light. The codes indicate what scheduled maintenance services and inspections are required at the given time and mileage for the vehicle. On modern-era cars the logic/algorithm behind the maintenance schedule and indicator light goes beyond the simple time and mileage tracking of past systems. Now things such as key cycles, engine warm ups, on/off time, as well as other driving characteristics are used to determine the necessary maintenance services. Contact one of our team members to discuss the maintenance schedule and make plans for your specific vehicle.
