Computer Diagnostics

 
Not all warning lights mean the same as they tend to vary depending on make and model. Referring to your owner's manual will make it easier to understand and identify warning symbols. Basically warning lights either tell you something in on, or indicate that a problem has occurred inside your car's system. At Wayne's Garage, our automotive specialists use the latest diagnostic technology to determine where and what problem is causing the light to illuminate.

Warning lights may vary in color in order to indicate the seriousness of a mechanical or system problem. 
  • A red warning light indicates either a potentially serious problem or safety issue, which should be attended to immediately by a professional. However, a red light might also serve as a reminder to the driver about service maintenance.
  • When a yellow or orange light activates, it's usually a signal that a component needs servicing or repair. If the light flashes, it's important to contact a repair shop or dealership.
  • Green and/or blue dashboard lights only serve to let the driver know that a system is active and operating.
Warning lights of a more serious nature: 
  • Brake warning light: Usually in red text, indicates a serious problem with the your brakes (main or emergency brakes).
  • Temperature warning light: If the symbol is red, it indicates your engine has overheated. A blue light means the coolant temperature is too low. Red and blue blinking means there is an electrical wiring malfunction.
  • Oil warning light can indicate low pressure.  
  • Battery charging system warning light: means either a bad battery or a failing alternator.
