DTC Descriptor
DTC B0052: Deployment CommandedCircuit/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 deployment loops, deploying the air bags and/or pretensioners causing DTC B0052 to set.
Conditions for Running the DTC
Ignition voltage is between 9-16 V.
Conditions for Setting the DTC
| • | 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. |
Action Taken When the DTC Sets
The SDM requests the instrument panel cluster to illuminate the AIR BAG indicator.
Conditions for Clearing the DTC
DTC B0052 is a latched code. The code cannot be cleared with the scan tool. Replacement of the SDM is required.
