PTH 003509.01 – Sensor Supply Voltage Data Valid but Below Normal Operational Range – Most Severe Level
PTH 003509.01 (PTH 3509.01)
Code: 003509.01
Shortcode: 3509.01
Description:
This fault code indicates that the sensor supply voltage (5 V) is below the normal operating range or is shorted to ground. This can result from issues with the hand throttle, wiring problems, or malfunctions in the power train hydrostatic control unit.
Reaction:
When this error is detected, the equipment may experience sensor-related issues, leading to improper operation or system shutdown to prevent damage.
Recommendations:
Inspect Hand Throttle (P03) Without ECU:
- Check the hand throttle for proper operation.
- Ensure the throttle is not damaged and is correctly positioned.
Test Power Train Hydrostatic Control Unit (PTH):
- Perform diagnostic tests on the control unit to identify any faults.
- Ensure all electrical connections to the control unit are tight and corrosion-free.
Check Wiring and Connections:
- Inspect the wiring harness connected to the hand throttle for any signs of damage, wear, or loose connections.
- Repair or replace any damaged wiring as necessary.
Update Control Software:
- Ensure the control unit software is up-to-date with the latest fixes and improvements.
Consult Technical Support:
- If the issue persists, contact technical support for further diagnostics and potential component replacement.
Monitor System Performance:
- After addressing the issue, monitor the sensor supply voltage to ensure normal operation and that the fault does not reappear.
Note:
Regular inspection and maintenance of the hand throttle and associated wiring can prevent this fault. Consider environmental factors such as extreme temperatures or moisture that can impact sensor performance.
