Underneath a cover by the driver side sliding door - where the passenger seat-belt is anchored, there is a black box that moans. We unplugged it and the van works fine. Hard to read the numbers on it but looks like CHB5127001. Is it something to do with the leveling system? The air compressor still works when this box is unplugged.

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.

The interior fuse box in a Pontiac Bonneville is underneath the backseat on the driver's side.

To remove the rear seat cushion:
1. Pull up on the front of the cushion to release the
front hooks.
2. Pull the cushion up and out toward the front of
the vehicle.

To reinstall the rear seat cushion:

1. Buckle the center passenger position safety belt, then
route the safety belts through the proper slots in the
seat cushion. Don't let the safety belts get twisted.
2. Slide the rear of the cushion up and under the
seatback so the rear - locating guides hook into the
wire loops on the back frame.
3. With the seat cushion lowered, push rearward and
then press down on the seat cushion until the spring
locks on both ends engage.
4. Check to make sure the safety belts are properly
routed and that no portion of any safety belt is
trapped under the seat. Also make sure the seat
cushion is secured.

Notice:
The battery and main fuse blocks are located
under the rear seat cushion. The battery's ground
terminal and some relay wires are exposed.
To help avoid damage to the battery and wires,
be careful when removing or reinstalling the seat
cushion. Do not remove covers from covered
parts. Do not store anything under the seat, as
objects could touch exposed wires and cause
a short.

no you need a driver side seat

Maybe a bad switch or something in the belt latch,
I unplugged mine at the floor where the right belt anchors,
Now it's quiet,I still know if the belt is on or not by the way it feels !!

The fuses for the seat are shared with other features on the car such as power antenna. Has any other power feature gone off as well?
Check the runners the seat slides in. There might be something trapped in there blocking the running action.
There are two fuse boxes. One under the hood in the rear drivers side corner, under a black plastic cover. The other is inside the car, inside the end panel of the dash. (With the door open).
Check fuses 1 and 18 as they cover the power seat functions.
