Thanks for using JA. My name is ***** ***** I will be happy to assist you in finding that code. cab 33 spn 521921, can relate to three different codes. Do you have the FMI number that follows the SPN number? It should either be a 3, 5, or 6. The three possible codes all relate to the same thing, but do help pinpoint the issue.
