The loaded record is too short. Necessary action: Load a new record. Record copying process from EEPROM to RAM was not successful. Necessary action: Replace the control unit. No valid adaptation data in the EEPROM. Necessary action: Replace the control unit. Fault in the allocation table of the record for digital I/Os. Necessary action: Load a new record. System interrupt duration has exceeded 10 ms. If this message occurs frequently, please inform your VOITH representative. Necessary action: Delete the error memory Test of the 2nd shutdown path by the safety computer unsuccessful. Necessary action: Check the dS relay! In diagnosis function G (test of the 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. Internal SW fault in digital_in(). Internal SW fault in digital_out(). Incorrect record checksum. Necessary action: Load a new record. Incorrect EPROM checksum. Necessary action: Load new software. No valid record in the EEPROM. The record was not completely loaded. Necessary action: Load a new record. No solenoid valve supply voltage (dS relay defective) or disrupted communication between microcomputer and safety computer during the initialization phase. Necessary action: Check the dS relay. Control unit not adjusted, resulting in wrong solenoid valve pressure values. Necessary action: Replace control unit. The reference voltage value of the AD converter is not in the allowed range betweeen 4.6 V and 5.4 V Necessary action: Replace control unit. The function "blockcopy_eeprom()" was called with incorrect or meaningless parameters. Necessary action: Inform customer service. An error occurred when you tried to add an error to the lined list of the FSP. Necessary action: Inform customer service. CAN bus hardware fault Fault handling: Check the CAN bus line No terminating resistors (together approx. 60 ohm)? Short-circuit between CAN-L and CAN-H? CAN-L short-circuit to supply voltage? CAN-H short-circuit to ground or supply voltage? CAN-H or CAN-L line interruption? CAN-H swapped with CAN-L line? Timeout due to the engine control unit Fault handling: It must be ensured that the engine control unit supports communication to SAE-J1939 via CAN bus. Is the engine control unit reporting any possible faults? CAN module is not installed In this case, the control unit is unsuited for CAN communication with an engine control unit. Fault correction: Use a control unit with a CAN module or Use the correct record (without CAN communication!) No valid CAN protocol set in the record. Fault correction: Replace the record. Engine control unit does not transmit a reference torque. It is probably not configured properly.
