Common Causes of B1B71 RAM

  1. Electrical issues such as a short circuit or open circuit in the sensor wiring.
  2. Physical damage to the sensor due to impact or corrosion.
  3. Faulty sensor components or internal circuitry.
  4. Poor connections or loose wiring in the sensor system.

Symptoms of B1B71 RAM

  1. Airbag warning light illuminated on the dashboard.
  2. Inconsistent or delayed airbag deployment in a collision.
  3. Increased sensitivity or false alarms from the airbag system.
  4. Vehicle may fail safety inspections due to airbag system issues.

How to Fix B1B71 RAM

  1. Begin by diagnosing the specific cause of the B1B71 RAM code using a diagnostic scanner to pinpoint the exact issue.
  2. Inspect the sensor wiring and connections for any signs of damage or corrosion, repairing or replacing as necessary.
  3. Test the sensor's internal components for proper functionality and replace the sensor if it is found to be faulty.
  4. Clear the DTC from the vehicle's computer system and test the airbag system to ensure proper operation.
  5. Reset the airbag warning light on the dashboard if necessary.

Cost to Fix B1B71 RAM

The typical repair costs for addressing the B1B71 RAM code can vary depending on the specific cause of the issue and the vehicle's make and model. In general, replacing a faulty acceleration sensor can cost anywhere from $200 to $500, including parts and labor. Additional costs may be incurred if wiring repairs or other components need to be addressed. It is advisable to consult with a qualified mechanic or auto repair shop to obtain a more accurate estimate based on the individual circumstances of the vehicle. Keep in mind that labor rates at auto repair shops can vary, so it's recommended to research local rates for a more precise cost estimate.

When is the Code Detected?

This Diagnostic Trouble Code (DTC) sets when the Occupant Restraint Controller (ORC) receives notification of a self test failure within the impact sensor. Once set, this DTC is latched for this entire ignition cycle. The DTC will be latched on the next ignition cycle only if it sets all the items for the fault.

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 B1B71 RAM Code

1. What does the OBDII code B1B71 mean in a RAM vehicle?

The B1B71 code indicates an issue with the Up-Front Right Satellite Acceleration Sensor, specifically an internal fault or malfunction.

2. What are the common symptoms of the B1B71 code in a RAM?

Common symptoms may include an illuminated airbag warning light, a disabled airbag system, or no noticeable performance changes but potential safety concerns.

3. What causes the B1B71 code to appear?

This code is typically caused by a faulty right satellite acceleration sensor, wiring issues, poor electrical connections, or, in rare cases, a malfunction in the airbag control module.

4. Can I drive my RAM with the B1B71 code active?

While the vehicle may still be drivable, the airbag system may not function properly in the event of a collision, which poses a significant safety risk.

5. How do I diagnose the B1B71 code in my RAM?

Diagnosis involves using an OBDII scanner to confirm the code, visually inspecting the sensor and wiring for damage, and testing the sensor with specialized tools if necessary.

6. How can I fix the B1B71 code in my RAM?

Repairs may include replacing the faulty acceleration sensor, repairing damaged wiring or connections, or, less commonly, replacing the airbag control module.

7. How much does it cost to repair the B1B71 code?

The repair cost can vary, but replacing an acceleration sensor typically ranges from $100 to $300, including parts and labor.

8. Can I clear the B1B71 code without fixing the issue?

Clearing the code without fixing the root cause is not recommended, as the airbag system may remain impaired and the code is likely to return.

9. Is the B1B71 code covered under my RAM vehicle's warranty?

It may be covered under the warranty if your vehicle is still within the warranty period and the fault is due to a manufacturing defect. Check with your dealer for specifics.

10. Can a software update fix the B1B71 code?

A software update is unlikely to resolve this code, as it typically points to a hardware issue with the sensor or wiring rather than a programming problem.
