IMPORTANT: Retrieving and utilizing Diagnostic Trouble Codes (DTC’s) for troubleshooting vehicle operation is only one part of an overall diagnostic strategy. Never replace a part based only on the Diagnostic Trouble Code Definition. Always consult the vehicle’s service manual for more detailed testing instructions. Each DTC has a set of testing procedures, instructions and flow charts that must be followed to confirm the exact location of the problem. This type of information is found in the vehicle’s service manual.
