Ignition Timing

The ignition timing cannot be adjusted; however, verifying
ignition timing can aid in troubleshooting other compo-
nents. To verify engine timing, see Periodic Maintenance.
KC280 Diagnostic Trouble
If an EFI or related chassis component fails or an out-of-
tolerance signal is detected by the ECU, a diagnostic
trouble code (DTC) will be generated in the ECU and
displayed on the LCD. For the first thirty seconds, the
LCD will go blank and the DTC will be displayed alter-
nately with a wrench icon or malfunction indicator light
(MIL). After thirty seconds, the digital display will return
to normal; however, the MIL and DTC will continue to
flash.
Code List
NOTE: Each of the following numerical codes will
have a one-letter prefix of C or P. A "C" prefix
denotes a chassis malfunction and a "P" prefix
denotes a power train malfunction.
 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.
