INSTRUMENT CLUSTER TROUBLE CODE
DISPLAY
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.
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.
Use the "Diagnostic Trouble Code Table" as a reference
(refer to the following pages).
