12.2 Fault codes
The fault codes can be useful in case of malfunction of the DFGT. Table below contains an overview of all possible
fault codes, their cause and possible action to solve the problem. The actual value of the fault (Table 7) can be
read by the DFRC, DFRC-SE, BRDG and BLE device. The ESYS fault (Table 7 and 8) can also be read by the
DFRC using setting Tag 57.
