CODE RETRIEVAL PROCEDURE<br />
12. Follow the testing and repair procedures outlined in the vehicle's<br />
service repair manual to correct "hard" DTCs. Codes should be<br />
addressed and eliminated in the order they were received, erasing<br />
(see SERVICING DTCs - OBD I on page 97) and retesting after<br />
each repair is made to be sure the fault was eliminated.<br />
The green, yellow and red LEDs are used (with the LCD<br />
display) as visual aids to make it easier to determine engine<br />
system conditions. See SERVICING DTCs - OBD I on page 97<br />
for information on interpreting LEDs and servicing DTCs.<br />
