Cost to Fix B1B70 RAM

The cost of repairing a B1B70 RAM code related to the Up-Front Left Satellite Acceleration Sensor Internal can vary depending on the specific cause of the issue and the vehicle's make and model. In general, the cost of replacing the sensor itself can range from $200 to $500, including parts and labor. Additional costs may be incurred if there are other underlying issues that need to be addressed. It is recommended to consult with a qualified mechanic or auto repair shop to get an accurate estimate based on the individual circumstances of the vehicle. Keep in mind that labor rates can vary, with typical rates ranging from $80 to $150 per hour.

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.
