CODE RETRIEVAL PROCEDURE<br />
Retrieving and using Diagnostic Trouble Codes (DTCs) for<br />
troubleshooting vehicle operation is only one part of an<br />
overall diagnostic strategy.<br />
Never replace a part based only on the DTC<br />
definition. Each DTC has a set of testing procedures,<br />
instructions and flow charts that must be followed to<br />
confirm the location of the problem. This information<br />
is found in the vehicle’s service manual. Always refer to<br />
the vehicle’s service manual for detailed testing<br />
instructions.<br />
Check your vehicle thoroughly before performing<br />
any test. See BEFORE YOU BEGIN on page 31 for details.<br />
ALWAYS observe safety precautions whenever working on a<br />
vehicle. See Safety Precautions on page 3 for more information.<br />
