DTC B1001 46
- Option Configuration Error
DTC B1001 4B
- Option Configuration Error Calibration Not Learned
Circuit/System Description
Some control modules must be configured with serial numbers, vehicle options, or other information. If a control module was not properly
configured after installation, that module may set DTC B1001.
Conditions for Running the DTC
Battery voltage is between 9-16 volts and data link communications operate normally.
Conditions for Setting the DTC
The control module is not configured properly.
Conditions for Clearing the DTC
* A current DTC clears when the malfunction is no longer present.
* A history DTC clears when the module ignition cycle counter reaches the reset threshold, without a repeat of the malfunction.
Circuit/System Verification
1. Program or configure the module or related module that set DTC B1001. The module should successfully configure.
锟斤拷 If the module will not configure, replace the module that set the DTC.
2. With a scan tool, clear the DTC.
3. Ignition OFF, remove the scan tool, open and close the drivers door.
4. Wait 60 seconds, then recheck for DTCs. DTC B1001 should not set.
锟斤拷 If DTC B1001 sets, replace the module.

DTC Descriptor
DTC B1001 00
- SDM Option Configuration Error
Circuit/System Description
The inflatable restraint sensing and diagnostic module (SDM) stores a primary data key, which is a 4-digit number, and a secondary data key, which
is a portion of the vehicle identification number (VIN). When the ignition is turned ON, the SDM compares this information to the information
stored in the body control module (BCM) over the serial data communication circuit.
Conditions for Running the DTC
Ignition voltage is between 9-16 V.
