Official summary
Many body control module C (BCMC) warranty return parts are coming back with no trouble found. To verify that the BCMC is at fault prior to replacing, perform the following. First, disconnect the battery then check all BCMC connectors for terminal pushout, pin damage, spread terminals, and corrosion. Refer to Workshop Manual Section 100-00 Wire Terminal Inspection and Replacement. If none found, reconnect the BCMC and battery terminals then recheck functionality. If concern still exists, proceed with BCMC replacement.
Vehicles covered
What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
