Description The control unit has detected an illegal condition and entered a corresponding fault number in the fault memory. This message usually occurs in connection with loading a data record or software. You have probably loaded a data record and/or software into your control unit which are not calibrated to each other. The following fault types exist:
Fault type | Troubleshooting
The loaded data record is too short for this software version | Load new data record.
Copying data record from EEPROM to RAM unsuccessful | Replace control unit
No valid adaptation data in EEPROM | Replace control unit
Fault in assignment table of data record for digital inputs/outputs | Load new data record.
System interrupt duration has exceeded 10 ms. If this message occurs more frequently, please inform the VOITH customer service. | Clear the fault memory .
Test of 2nd shutdown path by the safety computer unsuccessful | Check dS relay! In diagnosis function G (test of solenoid valves and relays), the voltage controlled by the dS relay is displayed as the SV supply voltage.
Fault in AD conversion or PEC transfer | Inform VOITH customer service
Internal SW fault in digital_in()
Internal SW fault in digital_out()
Incorrect record checksum | Load new data record.
Incorrect EEPROM checksum | Load new software
No valid data record in EEPROM The data record was not completely loaded. | Load new data record.
No solenoid valve supply voltage (dS relay defective) or faulted communication between main computer and safety computer during the initialization phase. | Check dS relay!
Control unit not calibrated. This results in incorrect solenoid valve pressure values. | Replace transmission control unit.
The reference voltage value of the AD converter is not in the legal range between 4.6 V and 5.4 V. | Replace transmission control unit.
The function "blockcopy_eeprom()" was called with incorrect or meaningless parameters. | Inform VOITH customer service
Fault in the safety computer interface. Calculation of desired PWM modulated braking effort to safety computer was cut off.
Data record is set to WE transmission, the control unit is however not equipped with REA1.
An error occurred trying to add a fault to the linked list of the fault memory.
