WARNING: This page is about a different car, the 1998 Oldsmobile Cutlass and 1998 Chevrolet Malibu. However, it is still accessible from the selected car via links, so may be relevant.

BFC uses circuit No. 156 (White wire) to ground interior lights. DTC B2558 will set when interior light relay is on (but not in theater or step dim lighting modes) and interior light feedback from circuit No. 156 (White wire) does not exist for .5 second. When DTC B2558 is set, interior light relay will turn off. DTC B2558 can be cleared when fault state is exited when status of interior lights returns to OFF. DTC B2558 can also be cleared using scan tool or when fault conditions no longer exist.
