Action in permanent fault
state
Restart the relay. If recov-
ered by restarting, contin-
ue relay normal operation.
If not recover by restarting,
check LHMI connection ca-
ble and connection to be
proberly fixed. If then not
recovered by restarting, ex-
change the LHMI module.
Restart the relay. If recov-
ered by restarting, contin-
ue relay normal operation.
If not recover by restarting,

recovered by restarting, ex-
change the LHMI module.
Restart the relay. If recov-

If not recover by restart-
ing, replace the relay, most
probably hardware failure
in CPU module.
