The hydrostatic motor temperature sensor B-46 (1) is located at the case drain tee at the top of the hydrostatic
motor, and monitors the temperature of the case drain oil exiting the motor. The sensor is connected (X091) to the
lower frame (LF) harness, and provides an input to the CCM1 module at connector X020 pin J3-33. The hydrostatic
motor temperature sensor B-46 circuit is also monitored by the CCM1 module; in the event that a fault occurs with
the sensor itself or the wiring to the sensor, a fault code will be displayed to the operator.

E0023-05 - Hydrostat Motor Temperature Sensor
The input from the hydrostatic motor temperature sensor B-46 is used to support the Temperature Control System
(TCS). CCM1 monitors the temperature of the case drain oil at 10 second intervals; if the temperature of the case
drain oil exceeds 105 °C, the hydrostatic pump will be de-stroked at increments of 5 - 10 %, depending on the level
of cooling required, until the oil temperature is reduced to 100 °C for at least 10 seconds.
