7.1 THE "CHECK ENGINE" LIGHT
Normally, the "check engine" light should come on when the ignition is turned on, then go out a few
moments after the engine starts running. If it reappears, or stays on while the engine is running, the
computer has detected a problem and a trouble code has been set.
NOTE: Most likely the check engine light will come on and stay on when using a computer with the
original factory programming this is normal and is why we recommended that the computer be
reprogrammed to remove any items that the factory vehicle had that aren’t being used in the vehicle
you are installing the engine into.
7.2 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 a Camaro/Firebird repair manual. This
will tell you 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.
