Lamp For Low Oil Pressure (Only Applies To Versions With Oil Pressure Sensor)

The oil pressure sensor (7/6) is connected to the engine control module (ECM) (4/46). The engine control module transmits the oil pressure signal onwards via the high speed section of the Control Area Network (CAN). The central electronic module (4/56) receives the signal, and generates a corresponding signal on the low speed section of the Control Area Network (CAN). If the oil pressure is low, the driver information module (DIM) (5/1) reads the signal from the low speed section of the Control Area Network (CAN). The driver information module indicates this to the driver by lighting a red warning lamp and displaying a text string with explanatory information.

HINT: In vehicles with an oil level sensor, the general warning lamp comes on and a text message appears when the oil level is too low.
