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

WARNING: This page does not describe the selected car, but rather 9 other vehicles, including the 2009 Volvo S60, 2008 Volvo S60, 2007 Volvo S60, 2006 Volvo S60, and 2005 Volvo S60. However, it is still accessible from the selected car via links, so may be relevant.

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.

HINT: For information about whether the vehicle is equipped with an oil pressure or oil level sensor, see Design and Function, Engine control module (ECM).
