Gauge For Transmission Oil Data
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.
