Description
Cause
Remedy
UCFG
VLP Unconfigured
(Diag3018)
/ VLP is
unconfigured and not
communicating with
I/O modules
Usually due to:
•
Incorrect MCF CRC;
•
MCF not loaded
•
MCF not stored in ECD
(ECD replaced);
•
No ATCS Site ID (SIN)
entered for Vital Comms
application
Check other diagnostic message for the exact
cause.
The normal sequence of messages seen on the four-character display when a CPU III is
booting up (4000 MCF shown here) is shown below:
CPU3 > Boot > Init > E087 > ICHK > CP MEF > VLP MEF > GCP 4k MCF
If a CPU III is inserted into a system that does not have the MCF loaded it will need to load the
MCF from the ECD, in this case, the boot up message sequence is shown below:
CPU3 > Boot > Init > E087 > ICHK > CRC UCFG > NRBT > Loading MCF > Burning MCF >
DONE > Boot > IP : Laptop > Init > ICHK > CP MEF > VLP ME > GCP 4k MCF
Note the E087 may or may not be present in the sequence above.
If the CPU III has been unpowered for more than a week and then it is inserted into a system,
the boot up sequence may show the following:
CPU3 > Boot > Init > E087 > ICHK > CRC.. UCFG.. ERR ..ECD
In this case, leave the CPU III installed in the system with power on for 1 minute, then remove
the CPU III module and reinsert it and it should boot up normally showing one of the first two
sequences shown above.
NOTE
If the CPU III has been unpowered for more than a week and then it
is inserted into an existing system it may show UCFG ERR ECD.
In this case, leave the CPU III installed in the system with power on
for 1 minute, then remove the CPU III module and reinsert it and it
should boot up normally showing one of the first two sequences.
