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.
| 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. |
