B1001 code What is a B1001 code and how can I fix the problem?

You might have your catalytic converter flow tested.

You replaced the SDM , was it programmed ?

What code ? Plugging in a scan tool to check codes is how it's done , not by the light blinking an then staying on . Your best bet , take it to a qualified repair shop.

AIR BAG Indicator
The AIR BAG indicator, located in the 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 and the IPC are supplied with ignition 1 voltage. The IPC responds by flashing the AIR BAG indicator seven times. While the IPC is flashing the AIR BAG indicator, the SDM conducts tests on all SIR system components and circuits. If no malfunctions are detected, the SDM will command the IPC to turn the AIR BAG indicator OFF via Class 2 serial data. The SDM provides continuous monitoring of the inflator module circuits by conducting a sequence of checks. If a malfunction is detected, the SDM will store a DTC and command the IPC to turn the AIR BAG indicator ON via Class 2 serial data. The presence of a SIR system malfunction could result in non-deployment of the inflator modules in the event of a collision, or deployment of the inflator modules without the event of a collision. The AIR BAG indicator will remain ON until the malfunction has been repaired.


Code's on a factory or professional scan tool look like this
DTC B0012, B0013, B0014, B0016, B0017, or B0018
DTC B0022, B0024, B0026, B0042, B0043, or B0044
DTC B0028, B0029, or B0030
DTC B0040, B0041, or B0045
DTC B0051
DTC B0053
DTC B0057, B0058, or B0059
DTC B0064, B0065, or B0066
DTC B0077, B0078, B0079, B0080, B0081, or B0082
DTC B0100, B0101, B0102, B0103, B0104, or B0105
DTC B1001


Doesn't do the flashing light code thing .

Sorry dude but your going to have to take to the dealer !
DTC B1001 DTC B1025, B1035, B1045, or B1055 DTC B1259 DTC B1780
The radio does not function properly. The radio displays "CAL".
Install a scan tool. Turn ON the ignition, with the engine OFF. With the scan tool, perform the radio setup procedure. Refer to Radio Setup . Turn OFF the ignition. Turn ON the ignition, with the engine OFF.

You can't just replace parts like that .
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.

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.

I have the same problem with my 03 Vue. I found some people saying that you can install a bcm on your own and by turning the ignition on and off in a certain sequence it will program itself. However I personally am going to take my car to a dealer. You can try to find a shop that has a tech 2 scanner (gm specific scanner), but it's not easy to find.
