RPT 000177.19 – Transmission Oil Temperature Sensor, Fault
RPT 000177.19 (RPT 177.19)
Code: 000177.19
Shortcode: 177.19
Description:
This diagnostic trouble code, RPT 000177.19, is generated when the PTA or CCU control software cannot determine the temperature of the transmission oil and, therefore, cannot provide the CAN bus with any relevant data. This results in a transmitted replacement value, triggering the diagnostic trouble code in the RPT control software. When active, this fault also generates a diagnostic trouble code in the PTA or CCU control software, which takes priority over the RPT code.
Reaction:
When this error is detected, the functionality of the control software is significantly limited or entirely non-functional. This affects the overall performance of the equipment, leading to reduced efficiency or operational capability.
Recommendations:
Inspect Transmission Oil Temperature Sensor:
- Examine the transmission oil temperature sensor for any visible damage or disconnections.
- Ensure the sensor is securely mounted and connected properly.
Check Wiring and Connections:
- Inspect the wiring and connections between the transmission oil temperature sensor and the PTA or CCU for signs of damage, corrosion, or loose connections.
- Repair or replace any damaged wires or connectors.
Test Sensor Functionality:
- Use diagnostic tools to test the functionality of the transmission oil temperature sensor.
- Ensure the sensor is transmitting accurate data to the PTA or CCU.
Update Control Software:
- Verify that the PTA, CCU, and RPT control software are updated to the latest versions.
- Install any available patches or updates that address sensor communication issues.
Consult Technical Support:
- If the problem persists, consult with technical support or the equipment manufacturer for further assistance.
- Provide detailed error logs and diagnostic reports to aid in troubleshooting.
Monitor System Performance:
- After addressing the issue, monitor the system for any recurrence of the fault.
- Keep detailed records of any further errors or irregularities to assist in ongoing troubleshooting.
Note:
The priority of the PTA or CCU diagnostic trouble code over the RPT code highlights the importance of resolving issues at the PTA or CCU level first. Regular maintenance and inspections of sensors and wiring can prevent such faults from occurring.
