DIAGNOSTIC TROUBLE CODES (DTC)
If a related chassis component fails or an out-of-tolerance
signal is detected by the ECM, a diagnostic trouble code
(DTC) will be generated in the ECM and displayed on
the LCD. The DTC will be displayed alternately with a
wrench icon or malfunction indicator light (MIL). The
DTC will continue to flash until the malfunction is cor-
rected and the code cleared.
