NOTE: The Smart Junction Box (SJB) is also known as the Generic Electronic Module (GEM).
NOTE: Most powertrain (P-code) DTCs are diagnosed in Computers and Control Systems Information. If the P-code retrieved is not listed below,
refer to Computers and Control Systems Information to continue diagnostics.
NOTE: Some of these modules utilizes 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.
