Massey Ferguson 10.00.06 – AIRCON: Cab Temperature Sensor Short Circuit (AIRCON)

The voltage signal from the cab temperature sensor has dropped below the expected operating range, typically caused by a short to ground within the sensor itself or its wiring harness.

1. 1

   Locate the inside cab temperature sensor, typically mounted in the top right side of the interior fuse panel or near the roof/blower unit.

2. 2

   Inspect the sensor's electrical connector for corrosion, bent pins, or moisture intrusion.

3. 3

   Disconnect the sensor and use a multimeter to check the wiring harness between the AIRCON module and the sensor connector for a short to ground.

4. 4

   Measure the resistance across the pins of the cab temperature sensor. A reading of near 0 ohms confirms an internal short circuit, meaning the sensor has failed and must be replaced.

1. 1

   Disconnect Power

   Turn off the tractor and disconnect the negative battery terminal to prevent electrical damage.

2. 2

   Access the Sensor

   Remove the interior trim panels necessary to access the top right side of the fuse panel or the roof console where the sensor is mounted.

3. 3

   Disconnect

   Unplug the electrical connector from the faulty cab temperature sensor.

4. 4

   Remove

   Remove the mounting screws or retaining clips holding the sensor in place and extract the unit.

5. 5

   Install

   Insert the new cab temperature sensor and secure it with the mounting hardware.

6. 6

   Reconnect

   Plug the electrical connector back into the sensor, ensuring it clicks securely into place.

7. 7

   Reassemble

   Reinstall any interior trim panels that were removed.

8. 8

   Test

   Reconnect the battery. Use a diagnostic tool to clear the 10.00.06 fault code. Start the tractor and test the A/C system to ensure the cab temperature regulates correctly without throwing a new code.
