Code B1B73 RAM Description
The B1B73 RAM diagnostic trouble code (DTC) specifically refers to the Left Side Satellite Acceleration Sensor 2 Internal. This code indicates a problem with the internal circuitry of the acceleration sensor located on the left side of the vehicle. The acceleration sensor is a crucial component of the vehicle's safety system, as it helps detect sudden changes in speed or direction, allowing the vehicle's safety systems to react accordingly. When this sensor malfunctions, it can lead to issues with the vehicle's stability control, traction control, and airbag deployment systems.
Common Causes of B1B73 RAM
- Damaged or faulty left side satellite acceleration sensor.
- Wiring issues, such as a short circuit or open circuit in the sensor's wiring harness.
- Corrosion or contamination affecting the sensor's internal circuitry.
- Impact or physical damage to the sensor due to a collision or rough driving conditions.
- Electrical issues within the vehicle's safety system affecting the sensor's operation.
Symptoms of B1B73 RAM
- Illumination of the traction control or stability control warning light on the dashboard.
- Erratic behavior of the vehicle's stability control system, such as unexpected activation or deactivation.
- Poor traction or stability during cornering or braking.
- Inaccurate deployment of airbags in the event of a collision.
- Diagnostic trouble code B1B73 RAM stored in the vehicle's onboard computer system.
How to Fix B1B73 RAM
- Begin by diagnosing the specific cause of the B1B73 RAM code using a professional diagnostic scan tool.
- Inspect the left side satellite acceleration sensor for any visible damage or signs of wear.
- Check the sensor's wiring harness for any loose connections, corrosion, or damage.
- If necessary, replace the left side satellite acceleration sensor with a new, OEM-quality part.
- Clear the diagnostic trouble code from the vehicle's computer system and perform a test drive to ensure the issue has been resolved.
Cost to Fix B1B73 RAM
The typical repair costs for addressing the B1B73 RAM code can vary depending on the specific cause of the issue and the cost of parts and labor. In general, replacing the left side satellite acceleration sensor can cost anywhere from $200 to $500, including parts and labor. Additional costs may apply if there are wiring issues that need to be addressed or if other components of the vehicle's safety system require attention. It's important to note that diagnostic time and labor rates at auto repair shops can vary, so it's advisable to check with local shops for a more accurate estimate based on your vehicle make and model.

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.
