FAULT CODE TRANS 80
wheel speed sensor is measured too high
Cause:
If the transmission controller detected the transmission output RPM (wheel speed sensor signal) is too high for the
desired gear, this fault code will be recorded.
Possible failure modes:
1. Tractor was in over-speed condition, such as run down hill with load.
2. Wheel speed sensor problem.
3. Wiring harness problem between the wheel speed sensor and the transmission controller.
Solution:
The wheel speed sensor is hard wired to both the transmission controller and the instrumentation controller. The
wheel speed is displayed on the ICU when Radar is not present.
This fault code is most likely being recorded when tractor was in over-speed condition, such as runs down hill with
heavy load. In such case, fault code 79 may be recorded too.
If it is sure the tractor has not been in over-speed condition or the fault code is active in normal condition, go to the
following steps.
1. Troubleshooting by viewing the Instrumentation display
Disconnect Radar if equipped. The wheel speed from the wheel speed sensor will be displayed when tractor is
running.
Drive the tractor at different gears and watch the wheel speed.
If the speed display is normal, the wheel speed sensor is fine. The problem is more likely in the wiring connection
from the sensor to the transmission controller.
If the wheel speed display is higher than it should be, go to next steps.
2. Test the resistance of the transmission speed sensor:
Locate the transmission speed sensor on top of the transmission.
Disconnect connector C069 from the sensor.
Inspect the connector. Clean the connection.
Measure the sensor resistance between pin A and pin B.
The resistance should be around 3 k ohms.
If the resistance is much higher than 3K, the sensor coil may be damaged internally.
If the resistance is close to 0, there must be a shortage inside the sensor.
In either case, replace the transmission speed sensor.
If the resistance is close to 3k ohms, go to next step.
3. Check the wiring from the wheel speed sensor to the transmission controller.
There is good chance the higher than normal signal is coming from other signal sources.
Check from pin A of connector C069 to pin 34 of connector 351 and from pin B of connector C069 to the clean
ground.
Pay more attention to connections crossing along wheel speed sensor circuit, engine RPM signal circuit, and PTO
speed signal circuit.
Looking for wiring shortage, loose connectors, and bent pins.
4. Check the function of the wheel speed sensor
