DTC B1001
Diagnostic Instructions
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) via the serial
data. 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.
Action Taken When the DTC Sets
| • |
The SDM requests the
instrument cluster to illuminate the AIR BAG indicator.
|
| • |
The SDM disables all
deployments. |
Conditions for Clearing the DTC
The last 4-digit Primary Data Key in the SDM matches the last 4
digits stored in the BCM.
Diagnostic Aids
| • |
This DTC is an indication that
an incorrect SDM is installed in the vehicle, or that the SDM
and/or the BCM was replaced without reprogramming the BCM with the
new information. |
