Gauge For Transmission Oil Data
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.
There is a gauge for transmission oil quality integrated into the software for the Transmission Control Module (TCM). This gauge calculates the time for which the oil exceeds a certain temperature during a certain period. When the gauge reaches the maximum value a diagnostic trouble code (DTC) for oil change is generated in the control module. When replacing transmission oil the gauge must be reset to zero to avoid generating a diagnostic trouble code (DTC) during incorrect conditions. This applies to changing transmission oil and when changing the oil with a repair.
The resetting function is activated via the vehicle communication input.
