DTC B1001 Option Configuration Error
When the ignition is turned ON, the inflatable restraint sensing and diagnostic module (SDM) compares the restraints ID that is stored in the SDM to the restraints ID that is stored in the body control module (BCM). The restraints ID that is being compared contains the last four digits of the SDM part number. Then, the SDM compares the VIN that is stored in the SDM to the VIN that is stored in the BCM. For more detailed information concerning the class 2 data lines, refer to Data Link Communications Description and Operation in Computer/Integrating Systems.
If the SDM is replaced you must setup the new SDM part number in the BCM. With a scan tool, select the SIR module setup. Select Setup SDM Part Number in BCM and follow the on-screen instructions. After, you must setup the new SDM. Select Setup New SDM and follow the on-screen instructions.

How do you know the theft system is the fault ? Security light lit on the dash ? What year , make an model vehicle ? Does it have transponder pellet in the head of the key ? If the security light is lit there is a code stored in the BCM , PCM , theft deterrent module ! Maybe you should admit defeat an take it to a ASE certified repair facility that knows about this stuff ! Before you make it none repairable !

Reset airbag light

Hey Earl, what's going on ? The air bag module is usually under the passenger seat or the center console ! The only way to turn off the light is with a up grade scan tool , not code reader. An the light is on for a reason , problem with the system ! If you don't know about this don't mess with it , you could deploy an air bag !
The AIR BAG indicator, located on the instrument panel cluster (IPC) is used to notify the driver of SIR system malfunctions and to verify that the SDM is communicating with the IPC. When the ignition is turned ON, the SDM is supplied with ignition 1 voltage and requests the IPC to flash the AIR BAG indicator 7 times. While flashing the indicator, the SDM conducts test on all SIR system components and circuits. If no malfunctions are detected the SDM will communicate with the IPC through the class 2 serial data circuit and request the IPC to turn the AIR BAG indicator OFF. The SDM provides continuous monitoring of the air bag circuits by conducting a sequence of checks. If a malfunction is detected the SDM will store a diagnostic trouble code (DTC) and request the IPC to turn the AIR BAG indicator ON. The presence of a SIR system malfunction could result in non-deployment of the air bags. The AIR BAG indicator will remain ON until the malfunction has been repaired.

How to solve obd code b1001 airbag configaration error

The problem is that the VIN an BCM numbers dont match. You are going to need a scan tool. Go into special functions setup from menu. Enter setup new BCM, do the same to the VIN SDM. If ithese numbers dont match an scan tool cant set it you will need to purchase a new BCM. Body Control Modual. It can be done but some vehicles dont allow it. May need a mechanic.

#PIC5913: Diagnostic Tip - B1001 With SIR MIL And/Or SVS MIL And/Or Locked Radio - (Sep 19, 2013)
Subject: Diagnostic Tip - B1001 With SIR MIL And/Or SVS MIL And/Or Locked Radio Models: 1998-02 Chevrolet Astro, Venture, S10, Blazer, Trailblazer, Camaro, Cavalier, Corvette, Impala, Monte Carlo, Lumina, Malibu, Metro, Prizm, Express 1998-02 GMC Safari, Savana 1998-02 Pontiac Bonneville 1998-02 Pontiac Firebird Models, Sunfire, Grand Am, Grand Prix, Montana 2001-02 Pontiac Aztek 1998-99 Buick Riviera 1998-02 Buick LeSabre, Park Avenue, Century, Regal 2002 Buick Rendezvous 1998-99 Oldsmobile Cutlass 1998-02 Oldsmobile Bravada, Aurora, Intrigue, Alero 1998-02 Cadillac DeVille, SeVille, Eldorado, STS, SLS, Catera, Escalade Models The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.
Condition/Concern Some vehicles may exhibit a B1001 DTC with an SIR lamp, SVS lamp on and/or radio locked, possibly after module replacement (i.e. BCM, SDM, etc.). This information is presented to clarify the failure modes that will set this DTC, as well as offer a diagnostic direction to help repair them.
DTC B1001, by definition, is a "configuration mismatch" between vehicle modules that communicate with each other over a data line. Modern vehicle systems depend upon each module storing certain vehicle information, as well as information about other modules in order to work properly together. Common causes of B1001 are:
  1. An incorrect or non-existent VIN number in modules that require them.
  2. A module that has been replaced but not programmed per currently published service information.
  3. SDM replacement where the new SDM is a different (newer) part number than the original.
Recommendation/Instructions A common diagnostic approach that will address most concerns with B1001 is as follows:
  1. Ask the technician if a module has recently been replaced which led to the B1001 DTC. If so, determine if the service information procedure for replacing the affected module has been followed. For example, some callers mistakenly believe that a new BCM simply requires "theft deterrent relearn" to operate properly. However, many modules require a "new module setup/RPO configuration" procedure to operate properly. The process for setting up a new module varies, consult currently published service information for the correct procedure for your application.
  2. If an SDM has recently been replaced, the BCM requires the last 4 digits of the SDM part number to be stored in a portion of the BCM to prevent DTC B1001. If the SDM's service part number is different than the original module, a special procedure is required to erase and re-learn this "restraints ID" code in the BCM. While the procedure varies from vehicle to vehicle, there are two standard methods as follows:
    1. On some vehicles the Tech 2 has a function available in the BCM or SIR "Special Functions" menu. Common terminology is "setup SDM part number in BCM" or similar nomenclature. Follow on-screen instructions to complete procedure.
    2. Some vehicles require an "SPS" method of programming the restraints ID. Perform the "Request Info" step at the vehicle and confirm the VIN number stored, then take the Tech 2 back to the terminal and down-load the appropriate file from the TIS2WEB "available modules" menu.
  3. If neither of the above are successful in clearing B1001, check the following modules with the appropriate Tech 2 data list under "VIN" or "module information" to determine if the correct VIN number is stored.
PCM: If the PCM does not have a VIN stored, or the incorrect VIN is stored, it will be necessary to program the PCM using the current SPS method. If the PCM already has the latest calibration software installed, it will be necessary to contact Techline Customer Support Center (TCSC: 1-800-828-6860 English or 1-800-503-3222 French) and request a VCI number to allow reprogramming with the same calibration.
BCM: If the BCM does not have a VIN stored, or the incorrect VIN is stored, it will be necessary to install the correct VIN using the appropriate line under the BCM's "special functions" menu. Follow on-screen prompts to complete programming.
Radio: If the Radio does not have a VIN stored, or the incorrect VIN is stored, it will be necessary to install the correct VIN using the appropriate line under the radio's "special functions" menu. Follow on-screen prompts to complete programming.
Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed.

Air bag light stays on

Whenever this warning light or any other stays on in the dash it is indicating that the systems control module (or the system sensor in the case of lights like low oil pressure, door open indicators etc.) has detected a fault, it then disables the system (this applies to ABS,TCS, TCM, SRS and BCM faults and others) as long as the light is on. You must now have the dealer hook up a special electronic diagnostic tool and "scan" the system for the fault code that is stored for the problem(s)

What does air bag code 43 mean?

The driver frontal loops 1 and 2 are the loops to the steering wheel air bag. The SDM(sensing and diagnostic module for the air bag) is seeing these circuits as open. There is a bullitin for problems with a loose connection for the yellow connector behind the left kick panel(right behind the e brake and hood release). I would remove the kick panel, and disconnect and reconnect the connector a couple times. See if the light goes out. Or wiggle and move the connector with the key on, as the light should go out if it makes good connection. If it does go out you need to replace this connector. Good luck.

• The SDM detects the air bag module deployment loop resistance is greater than 4.8 ohms for 500 milliseconds.

• The SDM detects that the voltage at the air bag module high control is less than 2.4 volts and deployment loop resistance is 6 ohms or greater for 500 milliseconds.
