NOTE: Only heated seat system related DTCs are listed. For all other HVAC module DTCs, refer to Multifunction Electronic Modules Testing and Inspection.

NOTE: This module 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 Diagnostic Trouble Codes (CMDTCs) have an additional 2-character DTC status code suffix to assist in determining DTC history.
