Why it is important to have ASE certified technicians properly maintain and service your vehicle. The technician you choose must understand the differences between various systems like ABS, TCS, BUS, SRS and other electrical systems important to keeping you safely on the road. Not only do they need to know these systems, they also need to know how to properly diagnose and repair them. Today's cars have more computer controlled electronics on-board and electric powered vehicles are already here. So the technician you choose needs a good understanding of computer controlled components as well as basic engine repair. AER will show you how having a competent technician working on your car, will cost you less money by finding the true problem and repairing it. AER identifies and verifies.
