DTC Descriptor



DTC B1001 00



- Option Configuration



Circuit/System Description



The inflatable restraint sensing and diagnostic module (SDM) stores a primary data key, which is a 4-digit number. 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. If there



is a mismatch between the information stored in the SDM and BCM, DTC B1001 will set.



Conditions for Running the DTC



System voltage is between 9-16 V.



Conditions for Setting the DTC



The 4-digit Primary Data Key stored in the SDM does not match the 4 digits stored in the BCM.
