Diagnostic Trouble Code Tests and Associated Procedures

Diagnostic Trouble Code (DTC) Chart

NOTE: The Body Control Module (BCM) 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.
