PAP ERROR CODES / PAP FAULT CODES

The PAP control software controls the solenoids for PTO speed.
Location: Without DirectDrive transmission – The PAP control software is included in the control unit for power-assisted rear PTO shifting (PAPTOS).
Location: With DirectDrive transmission – The PAP control software is included in the control unit for range shifting (DirectDrive transmission).
The PAP control software receives signals from the RPT control software via the vehicle CAN bus (500 kBd) and activates the relevant outputs for the solenoids. Signals are processed within the PAP control software and the following solenoid valves are activated depending on which speeds are selected for the rear PTO with power-assisted shifting (PAPTOS):
Without DirectDrive transmission
– Solenoid for PTO Speed 2 (PAPTOS), Component Information
– Solenoid for PTO Speed 1 (PAPTOS), Component Information
– Solenoid for PTO Speed 3 (PAPTOS), Component Information
With DirectDrive transmission
– 1/2/3 – Solenoids for PTO Speed (PAPTOS) (DirectDrive Transmission), Component Information

NOTE:This page only indicates the meaning of the fault codes. For complete troubleshooting information, see the technical manuals.

PAP 000628.12 (PAP 628.12)— Control Software, Internal Error
A fault occurred when the software was launched.
Reaction of the control software: Limited or no function of the control software.

PAP 000628.12 (PAP 628.12)— Control Software, Internal Error
A fault occurred when the software was launched.
Reaction of the control software: Limited or no function of the control software.

PAP 000629.12 (PAP 629.12)— Control Software, Internal Error
A fault occurred when the software was launched (watchdog).
Reaction of the control software: Limited or no function of the control software.

PAP 000630.02 (PAP 630.02)— Control Software Internal Fault
Error when reading the internal module (EEPROM).
Reaction of the control software: Limited or no function of the control software.

PAP 000639.12 (PAP 639.12)— Vehicle CAN Bus (500 kBd), High Error Rate
Unable to process all CAN Bus messages received. This is possibly caused by a CAN bus overload or an internal control software fault.
Reaction of the control software: Limited or no function of the control software.

PAP 000639.14 (PAP 639.14)— Vehicle CAN Bus (500 kBd), Very High Error Rate
Too many incorrect CAN Bus messages received. This indicates a general problem at the connection to the Vehicle CAN Bus (500 kBd).
Reaction of the control software: Limited or no function of the control software.
