To diagnose the B1B70 Jeep code, it typically requires 1.0 hour of labor.

It is common for most auto repair shops to charge between $75 and $150 per hour.
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.
Two front impact sensors are used on vehicles equipped with dual front airbags, one left side and one right side. One sensor is located on the back side of each vertical member of the radiator support. The impact sensors perform their own self test using power supplied by the Occupant Restraint Controller (ORC) then communicate this status back to the ORC with periodic updates. The impact sensor performs a self test for internal circuitry at power up during the initialization process, and continuously through the ignition cycle every 10 ms.
