TROUBLE CODE DISPLAY (DTC)
NOTICE
The diagnostic mode is accessible only when the check
engine MIL has been activated.
Use the following procedure to display diagnostic trouble
codes that were activated during current ignition cycle
causing the MIL to illuminate. Diagnostic trouble codes
will remain stored in the gauge (even if MIL turns off) until
the key is turned off.
NOTICE
If there is a diagnostic problem with the power steering
system, the power steering MIL will illuminate and blink
in place of the check engine MIL.
1. If the trouble code (s) are not displayed, use the
MODE button to toggle until “CK ENG” displays on
the information display area.
2. Press and hold the MODE button to enter the
diagnostics code menu.
3. A set of three numbers will appear in the information
area.
• The first number (located far left) can range from 0 to
9. This number represents the total number of trouble
code present (example: 2 means there are 3 codes
present).
• The second number (located top right) can be 2 to 6
digits in length. This is the suspect parameter number
(SPN).
• The third number (located bottom right) can be 1 to 2
digits in length. This is the fault mode indicator (FMI).
4. If more than one code exists, press the MODE button
to advance to the next trouble code.
5. To exit the diagnostic mode, press and hold the
MODE button or turn the ignition key OFF once the
codes are recorded.
