93 --- SA Fault Feedback Oil Actuator Basic unit has detected a ROM-CRC er-
ror on the oil actuator when checking its
feedback signal
Check CAN cabling and terminators as specified
If fault occurs sporadically: Improve EMC
If fault occurs constantly: Replace defective actuator
94 --- SA Fault Feedback Aux Actuator 1 Basic unit has detected a ROM-CRC er-
ror on the auxiliary actuator when check-
ing its feedback signal
Check CAN cabling and terminators as specified
If fault occurs sporadically: Improve EMC
If fault occurs constantly: Replace defective actuator

ror on the auxiliary actuator when check-
ing its feedback signal
Check CAN cabling and terminators as specified
If fault occurs sporadically: Improve EMC
If fault occurs constantly: Replace defective actuator
96 --- LC Fault Feedback Load Controller Basic unit has detected a ROM-CRC er-
ror on the load controller when checking
its feedback signal
If fault occurs sporadically: Improve EMC
If fault occurs constantly: Replace defective basic unit
97 --- ABE Fault Feedback AZL Basic unit has detected a ROM-CRC er-
ror on the AZL… when checking its feed-
back signal
Check CAN cabling and terminators as specified
If fault occurs sporadically: Improve EMC
If fault occurs constantly: Replace defective AZL…
98 --- All Fault two equal Addresses There are several components with the
same address on the CAN bus (CAN
overflow)
Check to see if several users (e.g. actuators) with the same
address are connected to the CAN bus and rectify (e.g. read-
dressing the actuators)
