HI,
PC based OBD-II Diagnostic Scanner can retrieve and describe both generic and manufacturer specific Diagnostic Trouble Codes (DTC's) giving you valuable information about why your check engine light (MIL) is illuminated.
Once a trouble code has been retrieved, you can use the scan tool to check for the cause by looking at live sensor data, emission related test results and sensor data from when the trouble code was set.
Once the problem is identified and repaired, the scan tool can reset the check engine light and clear the trouble code....
Thank you...
