Reading Diagnostic Trouble Codes

When the Malfunction Indicator Lamp (MIL) has been reported on, do the following:





1. Connect the Service Check Connector terminals with a jumper wire as shown. (The Service Check Connector is located behind the center console.) Turn the Ignition Switch on.





2. Note the Diagnostic Trouble Code (DTC): The MIL indicates a code by the length and number of blinks. The MIL can indicate multiple problems by blinking separate codes, one after another. Codes 1 through 9 are indicated by individual short blinks. Codes 10 through 43 are indicated by a series of long and short blinks. The number of long blinks equals the first digit, the number of short blinks equals the second digit. Sometimes the first blink is difficult to see; always count the blinks at least twice to verify the code.
