Read and interpret the Diagnostic Trouble Codes using the LCD display andthe green, yellow and red LEDs.The green, yellow and red LEDs are used (with the LCD display) asvisual aids to make it easier for the user to determine engine systemconditions.■ Green LED - Indicates that all enginesystems are "OK" and running normally. Allmonitors on the vehicle are active and areperforming their diagnostic testing, and notrouble codes are present. A zero will show onthe Car Reader’s LCD display for furtherconfirmation.■ Yellow LED - Indicates one of the followingconditions:PENDING CODE PRESENT - If the yellowLED is lit, it may indicate the existence of apending code.

This means that some of theMonitors on the vehicle have not yet finishedtheir diagnostic self-testing. This condition isconfirmed by one or more blinking Monitoricons on the LCD display. A blinking Monitoricon means the Monitor has not yet run andfinished its diagnostic self-testing. All Monitoricons that are solid have completed theirdiagnostic self-testing.■ Red LED - Indicates there is a problem withone or more of the vehicle's systems.
