Diagnostic Instructions

•	Perform the Diagnostic System Check - Vehicle prior to using this diagnostic procedure.

•	Review Strategy Based Diagnosis for an overview of the diagnostic approach.

•	Diagnostic Procedure Instructions provides an overview of each diagnostic category.

DTC Descriptors

DTC B0052 00: Deployment Commanded

DTC B0053 00: Deployment Commanded With Loop DTCs Present

DTC B0055 00: Side Airbag Deployment Commanded

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.

•	Deploying the side airbags causing DTC B0055 to set with no faults present.

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 requests the instrument panel cluster (IPC) to illuminate the AIR BAG warning lamp.

•	The SDM records crash data.

Conditions for Clearing the DTC

•	DTC B0052 can be cleared if the following conditions are met.

-	Three consecutive seat belt pretensioner deployment events have not occurred.

-	One frontal or side air bag deployment has not occurred.

•	DTC B0052 becomes a latched code after 3 consecutive pretensioner deployments or 1 frontal or side air bag deployment. The DTC is a latched code and cannot be cleared. Replace the SDM after following the instructions in the diagnostic test.

•	DTC B0055 is a latched code and cannot be cleared.

Circuit/System Verification

Important: The seat belt pretensioners may deploy for impacts that are not severe enough to warrant frontal or side air bag deployment. The SDM is capable of sustaining 3 pretensioner deployment events, or one frontal or side deployment event. After the maximum number of deployments has occurred, DTC B0052 sets and becomes a latched code, which cannot be cleared.

Verify DTC B0053 is not set.

⇒	If DTC B0053 is set along with additional DTCs, other than B0052, repair the malfunction causing the DTCs before replacing the SDM.

Verify DTC B0052 is not set.

⇒	If DTC B0052 is set, clear DTCs. If the DTC sets, replace the SDM.

Verify DTC B0055 is not set.

⇒	If DTC B0055 is set, replace SDM.

Repair Instructions

Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
