DTC Descriptors
DTC B0052 00
- Deployment Commanded
DTC B0053 00
- Deployment Commanded With Loop DTCs Present
DTC B0055 00
- Side Airbag Deployment Commanded
Circuit/System Description
The inflatable restraint sensing and diagnostic module (SDM) contains a sensing device that converts vehicle velocity changes into an electrical
signal. The SDM compares this electrical signal to a value stored in memory. When the generated signal exceeds the stored value, the SDM
performs additional signal processing and compares the generated signals to values stored in memory. When 2 of the generated signals exceed the
stored values, the SDM will cause current to flow through the appropriate deployment loops.
Conditions for Running the DTC
Ignition voltage is between 9-16 volts.
Conditions for Setting the DTC
B0052 00
* The SDM detects a frontal impact of sufficient force to warrant deployment of the frontal modules.
* The SDM detects a side impact of sufficient force to warrant deployment of a side impact module and/or roof rail module.
* The SDM has deployed the seat belt pretensioner for 3 separate deployments.
B0053 00
SDM commands inflators deployment with loop faults present.
B0055 00
* The SDM detects a frontal impact of sufficient force to warrant deployment of the frontal modules.
* The SDM detects a side impact of sufficient force to warrant deployment of a side impact module and/or roof rail module.
Action Taken When the DTC Sets
* The SDM will only set DTC B0052, or DTC B0055, or the SDM sets DTC B0053 along with DTC B0052.
* The SDM commands the AIR BAG warning lamp ON.
* The SDM records crash data.
Conditions for Clearing the DTC
* DTC B0052 can be cleared if the following conditions are met.
