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

Potential Causes:-

• Drivers Seat Belt Anchor Pretensioner
• Passengers Seat Belt Anchor Pretensioner
• Sensing Diagnostic Module (SDM)
• Sensing Diagnostic Module (SDM) Wiring

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.

Yes

there is a pretensioner in the seat belt buckles that go off when the air bags go off

There appears to be a pattern of premature failure of seatbelt pretensioners in the mid-2000s Gran Marquis, especially the 2005 model year. See carproblemzoo.com or NHTSA complaints. Ford dealer wanted $103 for diagnosis and $501 for replacement of the part.

There is a TSB to replace chafed wires on the seat belt pretensioners. Most common cause.
Both front seats have to be removed to perform the TSB. It involves replacing the male and female connector to the seat belt buckle pretensioner. In an accident, it fires and temporarily tightens the seat belt to take up slack. I think TSB 05-17-5.

b2292 is a body fault code.

This is a seat belt pretensioner code. You probsbly hsve s bsd connection on the seat belt buckle side along the console.

get the code, but my guess is it\'s the seat belt pre-tensioner connectors. There is a TSB to replace them on both seats at the same time. Not a recall so not covered under warranty. Please rate highly if this helps.

RESTRAINT SYSTEM - SAFETY BELT BUCKLE AND PRETENSIONER DIAGNOSTIC TROUBLE CODE (DTC) B1877 AND/OR B1881
FORD:
2001-2004 Escape

This article supersedes TSB 04-24-4 to update the service procedure.
ISSUE:
Some 2001-2004 Escape vehicles may exhibit an intermittent air bag lamp on and diagnostic trouble code (DTC) B1877 and/or B1881. This may be caused by a variation in the electrical continuity between the pins of the driver and/or passenger side wiring harness and the buckle pretensioner connector. If this condition were to occur, the air bag system remains fully functional.

ACTION:
Install a replacement harness connector kit ON BOTH the driver and passenger safety belt buckle pretensioners, even if the DTC is present for only one side. The kit includes improved connector halves to replace the existing connectors on both the body harness and the safety belt buckle pretensioner.
One kit is required per side (2 kits per vehicle). Refer to the instruction sheet included in the kit for complete repair procedure.

first, you need to read the Lamp Fault Code, LFC from the flashing light. Here's how:

Lamp Fault Codes
When the restraints control module (RCM) detects a system fault, it will cause the air bag indicator to flash a coded sequence: a lamp fault code (LFC). The code is two digits. The first digit is flashed with a 0.5 second interval between pulses. There is a 2 second pause before the second digit is flashed, which also has a 0.5 second interval between pulses. There is a 5 second pause between each display of an LFC.
Each LFC is flashed five times after which the air bag indictor will remain lit for the remainder of the key-on cycle. If there are multiple LFCs, each LFC will flash in order of priority.
-------------------------------------------------------
The fault could be in the air bag circuits, the canopy circuits, the pretensioner circuit on the seat belts, etc.
Report back with code.

here's some of system.

SECTION 501-20B: Supplemental Restraint System 2003 Expedition/Navigator Workshop Manual
DESCRIPTION AND OPERATION Air Bag and Safety Belt Pretensioner Supplemental Restraint System (SRS) The air bag supplemental restraint system (SRS) is designed to provide increased collision protection for front seat and second row outboard occupants in addition to that provided by the three-point safety belt system. Safety belt use is necessary to obtain the best occupant protection and to receive the full advantage of the SRS.
This vehicle line contains dual stage deployment (advanced restraint system) driver and front passenger air bag modules. These vehicles can also be equipped with optional safety canopies that deploy from the A-pillar to the C-pillar upon a side impact or if a rollover condition is detected. If equipped with safety canopies, a unique restraints control module (RCM) is used.
See the following illustration for deployable component location.
