1. Battery voltage with engine and accessories off
(>12.2 VDC for fully charged).
2. Battery voltage with engine running (charging = 13.8
VDC or greater).
3. Battery voltage with electrical accessories operating,
engine idling (13.5 VDC or greater).
4. Battery voltage starter cranking (10.5-11.5 VDC).
DIAGNOSTIC TROUBLE CODES
(DTC)
If an EFI or related chassis component fails or an out-of-
tolerance signal is detected by the ECM, a diagnostic trou-
ble code (DTC) will be generated in the ECM and dis-
played on the LCD. The DTC will continue to flash until
the malfunction is corrected and the code cleared.
Code List
NOTE: Each of the following numerical codes will
have a one-letter prefix of C, P, or U. A “C” prefix
denotes a chassis malfunction, a “P” prefix
denotes a power train malfunction, and a “U” pre-
fix denotes a loss of communication with the
gauge.
NOTE: Normal malfunction codes are cleared from
the LCD when the component is replaced or the mal-
function is corrected; however, intermittent codes
must be cleared as noted in the code chart.
