B2601 on Nissan
Body Control Circuit Fault (manufacturer-specific)
B2601 on Nissan vehicles indicates body control circuit fault (manufacturer-specific). Au7o has documented this code across 2 Nissan models — most commonly on Murano, Titan. 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. Typical repair costs on Nissan range from $180 to $1,200, depending on the specific model and root cause.
Common Causes of B2601
- •Shorted/grounded control circuit (e.g., DRL relay on some GM)
- •Wiring or connector damage and corrosion
- •Faulty relay, switch, or sensor in the affected circuit
- •Signal mismatch between modules (make-dependent)
- •Faulty body control module
- •Make-specific component fault per service manual
B2601 on Nissan by Model
Nissan Murano(1 issue)
- Battery Drain and No-Start from Telematics/Infotainment Modules Staying Awake2021-2024
A recurring owner complaint on newer Nissan crossovers, including Murano, is a dead battery after sitting overnight or for a few days despite the battery testing good initially. Reports often point to parasitic draw from telematics, AV control, or body control modules that fail to enter sleep mode, sometimes accompanied by app connectivity glitches or infotainment oddities. The issue can be intermittent, making it difficult to catch unless a proper draw test is performed after module timeout.
Nissan Titan(1 issue)
- Battery Drain and No-Start from Telematics/Audio Control Unit Staying Awake2020-2024
A recurring owner complaint on newer Titans is parasitic battery drain after sitting overnight or for several days, leading to slow cranking or a complete no-start. Reports frequently point to the infotainment, telematics, or body control network not going to sleep properly, especially after software glitches, accessory installation, or repeated short-trip use. Some owners replace the battery only to have the drain return until the underlying module issue is addressed.
