Bulb Check

The purpose of illuminating the instrument cluster PRNDL display and indicator displays during the power up of the instrument cluster is to verify that all segments of the PRNDL display and that all of the indicator displays are working properly.

The turn signal indicators do not turn ON during the bulb check. If an expected indicator or PRNDL segment does not function properly during the bulb check further diagnosis of the instrument cluster may be necessary. Refer to A Diagnostic System Check - Instrument Cluster
