Below code is able to solve your problem. I create tmp file which define the mapping array to be included in the BEGIN block in awk and it will be dynamically included in the second awk command to replace the 3rd field based on the mapping.

Code:
$ cat a.sh
#! /bin/sh

if [ $# -ne 2 ]; then
        echo "Usage: $0 <input.txt> <info.txt>"
        exit 1
fi


tmpfile=".tmpfile-$$"
trap "rm -f $tmpfile" 0 1 2 3 15


awk '
{
        printf("map[%d]=\"%s\";",$2,$3)
}' $2 > $tmpfile


awk '
BEGIN {FS=";";OFS=";";'`cat $tmpfile`'}
{
        print $1,$2,map[$3],$4
}' $1

$ ./a.sh input.txt info.txt
test-1;1;Pass;100Mb/s
test-2;1;Fail;
test-1;2;Fail;
test-2;2;Unknown;
test-2;3;Crash;

tmpfile

tmpfile(3S)															       tmpfile(3S)

NAME

       tmpfile() - create a temporary file

SYNOPSIS

DESCRIPTION

       creates	a temporary file by generating a name through (see tmpnam(3S)), and returns a corresponding pointer.  If the file cannot be opened
       a NULL pointer is returned.  The file is automatically deleted when the process using it terminates.  The file is opened for update

   Notes
       On HP-UX systems, the mode is equivalent to the mode.

ERRORS

       The function will fail if:

	      [EOVERFLOW]	       The named file is a regular file and the size of the file cannot be represented correctly in an	object	of
				       size in this environment.

       Additional values may be set by the underlying function (see fopen(3S)).

SEE ALSO

       creat(2), unlink(2), mktemp(3C), fopen(3S), fgetpos64(3S), tmpnam(3S), thread_safety(5).
