This diagnostic trouble code is generated when the PTA control software generates a diagnostic trouble code that is unknown to other control software. This general diagnostic trouble code enables the CommandCenter to display information relating to this unknown PTA diagnostic trouble code.

This diagnostic trouble code is generated when the PTA control software detects a difference in frequency between the two sensor output signals for hydrostatic speed, indicating that the speed at channel 1 is lower than at channel 2.

This diagnostic trouble code is generated when the PTA control software detects that the voltage at channel 1 of the hydrostatic speed sensor is too low. This indicates a short to ground in the sensor circuit.

This diagnostic trouble code is generated when the PTA control software detects that the voltage at channel 1 of the hydrostatic speed sensor is too high. This indicates a supply voltage problem or that the sensor circuit is open or shorted to a positive lead.

This diagnostic trouble code is generated when the filter bypass valve (for cold-weather starting) is open while the transmission input speed (engine speed) is above 1400 rpm and transmission oil temperature exceeds +30°C (86°F). If diagnostic trouble code PTA 000127.01 is also stored, process that code first.

This diagnostic trouble code is generated when the filter bypass valve (for cold-weather starting) is closed under the following conditions: Transmission input speed (engine speed) is above 1400 rpm and transmission oil temperature is below -5°C (23°F); engine is off. The diagnostic trouble code triggers the alarm level: Information.

This diagnostic trouble code is generated when the PTA control software receives the power zero signal from the TIA control software via the CAN BUS for more than 5 minutes.

This diagnostic trouble code is generated when the PTA control software detects that the park lock is engaged, even though Power Zero is commanded by the TIA control software at the same time.

READ MORE

This diagnostic trouble code is generated when the TIA control software is unable to determine the value for changing direction of travel (PSS) and cannot provide the CAN BUS with relevant data. A transmitted replacement value generates this diagnostic trouble code in the PTA control software.

This diagnostic trouble code is generated when the TIA control software is unable to determine the value for transmission shift monitor (RSL) and cannot provide the CAN BUS with relevant data. A transmitted replacement value generates this diagnostic trouble code in the PTA control software.
