Instrument Cluster Self-Test
To enter the instrument cluster self-test mode on the base instrument cluster, press and hold the instrument cluster trip odometer/reset button and turn the ignition switch to the RUN position until tESt appears in the integrated display. On instrument clusters equipped with a message center, press and hold the message center RESET button and turn the ignition switch to the RUN position until CLUSTER ENGINEER TEST appears in the message center. Press the trip odometer/reset or RESET button to advance through the displays. To exit the self-test mode, turn the ignition switch to the OFF position. If no DTCs related to the concern are retrieved, go to Symptom Chart .
