Know your warning symbols

At The FastFit Centre, we want you to get to know your car as well as we do. Although a majority of vehicle repairs require professional knowledge and expertise, there is a number of day to day things that you can look out for. Here is the Fastlane Autocare guide, 'Knowing Your Warning Symbols':

There is a series of warning symbols installed to your car, van, truck or motorhome. Commonly part of your vehicle's ECU and CAN-Bus system, these systems are designed to stop your vehicle from obtaining serious damage if a component fails.
