How to get lines which are unique for 1 column but are same for another column?

Question

I am looking for an awk solution which would fetch lines which are unique based on 2nd column when the 1st & 3rd and 4th columns are the same.

constraints :

1. column 3 and column 4 has to be same for the rows (two consecutinve rows sorted on the 3rd column)
2. if 1 is true, check if column 1 is same for those rows from step 1.
3. then check if rows from step 2 have same column 2 values , if not then print out the rows (both rows) else print none of both rows.

input file :-

AB|abcd|0001|Active
AB|efgh|0001|Active
AB|efgh|0001|Closed
CD|xyz|0002|Active
CD|pqr|0002|Active
EF|xyz|0003|Active
EF|xyz|0003|Closed

output :-

AB|abcd|0001|Active
AB|efgh|0001|Active
CD|xyz|0002|Active
CD|pqr|0002|Active

tried below code but it gives me same $2 values

awk -F'|' '
  BEGIN{OFS=FS}
  $4 ~ /Active/ && a[$3]++ && $2 != c {
    print r ORS $0
  }
  {r=$0; c=$2}' <(sort -k3,3 file)

Answer 1

<infile sort -t'|' -k3,4 -k1,2 |
 awk -F'|' '
     ($3==p[3] && $4==p[4] && $1==p[1] && $2!=p[2] ) && 
      NR>1{ print buf ORS $0; next }
     { buf=$0; split($0, p) }'
