B1119 Nissan Code - Left Air Bag Satellite Sensor
Quick Answer
When the Air Bag Diagnosis Sensor Unit (ACU) define the both signal voltage of the “G†sensor and the Safing sensor to be that of the collision which exceeds the specified level, the driving circuit switches on and feeds the electric ignitor of both the side air bag and curtain air bag. Common causes include Faulty Left Air Bag Satellite Sensor, Left Air Bag Satellite Sensor harness is open or shorted, Left Air Bag Satellite Sensor circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Precautions for SRS “AIR BAG” and “SEAT BELT PRE-TENSIONER” Service
- Never probe the electrical connectors on air bag, side air curtain modules or seat belts.
- Never disassemble or tamper with safety belt buckle/retractor pretensioners, adaptive load limiting retractors, safety belt inflators, or probe the electrical connectors.
- Do not use electrical test equipment to check SRS circuits unless instructed to in this Service Manual.
- Before servicing the SRS, turn ignition switch OFF, disconnect both battery cables and wait at least 3 minutes. For approximately 3 minutes after the cables are removed, it is still possible for the air bag and seat belt pre-tensioner to deploy. Therefore, do not work on any SRS connectors or wires until at least 3 minutes have passed.
Failure to follow this instruction may result in the accidental deployment of these modules, which increases the risk of serious personal injury or death.
Frequently Asked Questions about B1119 Nissan Code
1. What does the OBDII code B1119 mean for a Nissan?
The B1119 code indicates an issue with the Left Air Bag Satellite Sensor, which is responsible for detecting side impacts and triggering the airbag system.
2. What are the common symptoms of a B1119 code on a Nissan?
Common symptoms include an illuminated airbag warning light, the airbag system being disabled, or failure of the left side airbag to deploy in a collision.
3. What causes the B1119 code to appear?
This code can be triggered by a faulty left airbag satellite sensor, damaged wiring or connectors, corrosion in the sensor circuit, or water intrusion.
4. Is it safe to drive with a B1119 code present?
No, it is not safe, as the airbag system may not function properly in the event of an accident, increasing the risk of injury.
5. How can I diagnose the B1119 code on my Nissan?
Diagnosis involves using an OBDII scanner to confirm the code, visually inspecting the sensor and its wiring for damage or corrosion, and performing continuity tests on the circuit.
6. Can the B1119 code be cleared without repairs?
Clearing the code without addressing the underlying issue will not resolve the problem, and the airbag warning light will likely return.
7. How much does it cost to repair a B1119 code on a Nissan?
Repair costs can vary but typically range from $150 to $500, depending on whether the sensor, wiring, or other components need replacement.
8. Where is the Left Air Bag Satellite Sensor located?
The Left Air Bag Satellite Sensor is usually located near the left side of the vehicle, often in the door frame or under the seat.
9. Can I replace the Left Air Bag Satellite Sensor myself?
While replacement is possible for experienced DIYers, it’s recommended to have a professional handle it due to the complexity and safety risks involved with the airbag system.
10. What tools are needed to repair the B1119 code?
You’ll need an OBDII scanner, basic hand tools, and possibly a multimeter for circuit testing. Always disconnect the battery before working on the airbag system to avoid accidental deployment.
