Description
Field Variables Table
Checksum Error. The
verification checksum
for the main field
variable table has
failed. During power
outages or brown-
outs, enough noise
can be generated on
the 5V DC supply to
cause an error in
reading the field
variables table on
power up. For this
reason, we keep the
data in two separate
tables. If only one
table checksum error
occurs, then valid data
will be restored.
The Gate Switch failed
on while the door was
open.
The gate or lock
bypass switch was on
while the car was NOT
on car top inspection.
Governor Switch
Tripped.
GOVRi input failed on.
GRCan Bus Off Error.
The Can bus has been
inactive for too long a
period of time.
