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.
