NOTE: The Smart Junction Box (SJB) is also known as the Generic Electronic Module (GEM).

NOTE: Some of these modules utilize a 5-character DTC followed by a 2-character failure-type code. The failure-type code provides information about specific fault conditions such as opens, or shorts to ground. Continuous memory DTCs have an additional 2-character DTC status code suffix to assist in determining DTC history.
