B1049 on Nissan
Manufacturer-Specific Body Code (GM: Audio Output #3 Left-Rear Circuit Open)
B1049 on Nissan vehicles indicates manufacturer-specific body code (gm: audio output #3 left-rear circuit open). Au7o has documented this code across 2 Nissan models — most commonly on Rogue, Sentra. B1049 is a manufacturer-specific body code whose meaning depends on the vehicle maker. On GM/Chevrolet vehicles it generally refers to the audio amplifier output #3 (left-rear speaker) circuit being open, meaning the module detected a break in the wiring to that speaker. On some other makes a B1049 may map to a different body/comfort circuit, so the definition should be confirmed for the specific vehicle. It is typically a comfort/convenience fault rather than a safety issue. Typical repair costs on Nissan range from $300 to $900, depending on the specific model and root cause.
Common Causes of B1049
- •Open or broken wiring to the left-rear speaker
- •Faulty or blown speaker
- •Corroded or loose speaker connector
- •Damaged radio/amplifier output stage
- •Chafed or pinched harness behind trim or in door
- •Poor ground at the audio module
B1049 on Nissan by Model
Nissan Rogue(1 issue)
- Clock Spring / Spiral Cable Failure Causing Airbag Light and Loss of Steering Wheel Controls2008-2013
A known failure point on many Nissan models of this era is the steering wheel spiral cable (clock spring), which can break internally from repeated wheel rotation. On Rogue, owners report the airbag warning light illuminating along with loss of horn, cruise control, or audio controls on the steering wheel. Because it affects the driver airbag circuit, the issue has clear safety implications even if the vehicle remains drivable.
Nissan Sentra(1 issue)
- Steering Wheel Clock Spring Failure Causing Airbag Warning and Inoperative Steering Controls2023-2025
Some owners report airbag warning lights, loss of steering-wheel audio/cruise buttons, and intermittent horn operation traced to the spiral cable/clock spring assembly. When the clock spring develops an internal open circuit, it can interrupt communication and power to steering-wheel-mounted systems and potentially affect the driver's airbag circuit. While not every case results in an airbag fault, the safety implications make it significant.
