Code B001b is for Sensing Diagnostic Module (SDM) for Air bag.

1. Confirm the passenger seat belt anchor pre tensioner connector position assurance is clicked into place.

2. If not, click it in and retest.

3. If the codes reset, disable the Supplemental Inflatable Restraint (SIR) system.

4. Substitute a 2.0 to 2.2 ohm resistor for the passenger seat belt anchor pretensioner. Refer to Tech Tips for a load tool.

5. Retest for the code to reset.

6. If the code resets, check for harness problems between the seat belt anchor pretensioner and the Sensing Diagnostic Module (SDM).
Tech Tips: At the beginning of the 2009 model year, the Impala began being equipped with two pre tensioners for the driver and two pre tensioners for the front passenger. The first pretensioner is still attached to the seatbelt retractor. The second pretensioner is attached to the anchor point for the seat belt.
A load tool can be fashioned from an 1157 light bulb and socket. Turn the bulb into the socket. Using an ohmmeter, determine which 2 wires have 2 - 3 ohms of resistance. Use those 2 wires as the load tool.

The anchor points that you describe are on all late model cars. They're made for attaching baby car seats without using seat belts. Your car should have both the anchors AND seat belts. Most likely, the lower seat belt latches have beeb pushed down into the seat. Fish around with your hand and you should find them.

Good luck.
