CODE RETRIEVAL PROCEDURE
11. Follow the testing and repair procedures outlined in the vehicle's
service repair manual to correct "hard" DTCs. Codes should be
addressed and eliminated in the order they were received, erasing
(see Erasing DTC's on page 80) and retesting after each repair is
made to be sure the fault was eliminated.
The green, yellow and red LEDs are used (with the LCD dis-
play) as visual aids to make it easier to determine engine sys-
tem conditions. See Servicing Diagnostic Trouble Codes
on page 78 for information on interpreting LEDs and servic-
ing DTCs.
