Oil Level Warning

The oil level sensing system consists of the following components:
^ An oil level switch
^ The powertrain control module (PCM)

The oil level switch provides the oil level data to the PCM through CKT 174 (BRN). If the PCM determines that a low oil level condition exists, the PCM sends the low oil level message to the instrument cluster through the universal asynchronous receiving/transmitting (UART) serial data line CKT 800 (TAN). The instrument cluster transmits the data to the driver information center (DIC) through the UART B serial data line CKT 1061 (ORN/BLK). The DIC displays the CHECK OIL LEVEL warning when the data is received.
