A separate tool can also be used to reset the SRS system (separate from the engine diagnostic system). These tools can read and reset trouble codes and reset your maintenance interval settings. They are a must for the DIYer or any mechanic. These diagnostic tools pay for themselves. You can take the car to the dealer and have the code pulled for you (for a one-time fee) or you can buy one of these code readers and check the trouble code yourself (and any other code that may come up in the future).
The Check Engine or Service Engine Soon light means something! It's alerting you to a potential problem and a fault code has been stored in the car's internal diagnostic system. Fault Code Readers and Diagnostic Scanners put the power of the dealership in your hands.
