PCM Controlled Warning Lamps

The PCM controlled warning lamps are intended to alert the driver about an operating condition which may require immediate attention. The IP Cluster has a hierarchy for displaying messages. If the Rear Compartment Lid, Driver, or Passenger Doors are open this will take precedent over other messages such as low oil level or low oil pressure. It is imperative that all passenger doors and rear compartment lid be completely closed while diagnosing the warning lamps, or messages. For further information regarding warning lamps not controlled by the PCM refer to Instrument Cluster Circuit Description, Driver Information Center (DIC) or Message Center Description, Driver Information Center (DIC) or Message Center Operation, and Driver Information Center (DIC) or Message Center Circuit Description in Instrument Panel, Gauges, and Warning Indicators.
