With a code reader, diagnosing and clearing your check engine light is really just a plug and play deal. Depending on your budget, you can get a scan tool for the 30 to 40 dollar range. For our purposes, we chose the Innova FixAssist OBD2 scan tool for our job. It has a 2.8 in. all-in-one color screen, which displays show 20 pieces of vital information at one time, including trouble codes and their definitions. It can read and erase check engine light codes with the click of a button. Plus, it offers a battery/alternator test to help troubleshoot no-start problems and can diagnose and erase ABS codes as well. You can view livestream data or use the freeze frame mode to show engine conditions such as fuel trim and coolant temperatures with indicator lamp was lit.
