2 vehicles · 1 makes · $180-$1,200 repair
Most Reported On
B2601 is an OBD-II diagnostic trouble code meaning “Body Control Circuit Fault (manufacturer-specific).” This is a body code whose exact meaning is manufacturer-specific and varies widely by make. On some GM vehicles it indicates the daytime running lamp (DRL) relay control circuit is shorted to ground, while on Nissan/Infiniti it relates to a shift-position signal mismatch seen by the body control module, and on other vehicles it refers to a door latch/closing signal fault. In general it points to a circuit or signal problem detected by a body-system module, so the correct diagnosis depends on the specific vehicle's service information. This code is most commonly reported on 2021-2024 Nissan Murano, and 2020-2024 Nissan Titan, with repair costs ranging from $180 to $1,200.
