RETRIEVING TROUBLE CODES FROM THE COMPUTER
7.2.1
In order to retrieve the trouble codes stored in the computer, a scanner must be connected to the Assembly
Diagnostic Link (DLC) connector (installed and connected in Paragraph 6.2.1). Follow the instructions
provided with the scanner to read the codes set in the computer.
7.2.2
After you have read any codes, write them down for reference. Remove the connector from the DLC
connector.
7.2.3
Take the codes one at a time and match them to the codes in the 1997 C/K Truck repair manual. This will
tell you in which circuit the computer has detected a problem.
Note: A code indicates a problem in a specific circuit, NOT THAT A PARTICULAR PART IS
BAD.
7.2.4
Before taking more extensive corrective actions for any trouble codes make sure that all
connections on the indicated circuit, INCLUDING THE COMPUTER, are clean and tight.
Inspect the wiring in the circuit for any broken, shorted, or exposed wires. Finally, insure all
ground wires are clean and secure.
7.2.5
If a trouble code is detected and the problem has been fixed, clear the codes by first making sure the
ignition is off then disconnecting the NEGATIVE battery cable for at least 3 minutes.
