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.
