When installing a new instrument cluster, it is necessary to upload the module configuration to the diagnostic tool. Following installation of the instrument cluster, download the module configuration from the diagnostic tool into the new instrument cluster. For additional information, refer to MODULE CONFIGURATION . The following items are configurable:

The instrument cluster carries out a prove-out when the ignition switch is turned from the OFF to the RUN position to verify the integrity of the warning indicators. The charging system warning indicator, the low oil pressure warning indicator and the malfunction indicator lamp (MIL) illuminate when the ignition switch is turned to the ON position, and then turns off when the engine is started and running normally. The seat belt warning indicator proves-out for 60 seconds and then turns off, or turns off when the seat belt is fastened. The following indicators prove-out for 3 seconds when the ignition switch is turned to the ON position:
- air bag
- ABS
