Reading Codes

Print

On all models covered by this guide, an OBD-II compliant scan tool must be used to retrieve the Diagnostic Trouble Codes (DTCs). Follow the scan tool manufacturer's instructions on how to connect the scan tool to the vehicle's DLC and how to retrieve the codes.

DTCs come in four categories:



Type A, which will immediately set the Malfunction Indicator Light (MIL)
 
Type B, will set a MIL if the fault is present after two consecutive drive trips
 
Type C or D, will set as a DTC in memory, but will not turn on the MIL
