B0052

DTC B0052

Diagnostic Instructions

* Perform the Diagnostic System Check - Vehicle (See: Testing and Inspection/Initial Inspection and Diagnostic Overview/Diagnostic System

Check - Vehicle) prior to using the diagnostic procedure.

* Review Strategy Based Diagnosis (See: Testing and Inspection/Initial Inspection and Diagnostic Overview/Strategy Based Diagnosis) for an

overview of the diagnostic approach.

* Diagnostic Procedure Instructions (See: Testing and Inspection/Initial Inspection and Diagnostic Overview/Diagnostic Procedure

Instructions) provides an overview of each diagnostic category.

DTC Descriptor

DTC B0052 00

- Deployment Commanded Malfunction

DTC B0052 56

- Deployment Commanded Too Many Transitions

Circuit/System Description

The inflatable restraint sensing and diagnostic module (SDM) senses vehicle impacts and provides deployment signals to the air bags and anchor

and/or retractor pretensioners when warranted. The SDM sets DTC B0052 after each command for deployment. DTC B0052 will latch and not

clear until after 3 commanded deployments by the SDM. And therefore the SDM has to be replaced using end of life disposal procedure.

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 air bags.

* The SDM detects a side impact or rollover (if equipped) of sufficient force to warrant deployment of a seat side air bag and/or roof rail air

bag.

Action Taken When the DTC Sets

The SDM requests the instrument cluster to illuminate the AIR BAG indicator.

Conditions for Clearing the DTC

* DTC B0052 00 is a clearable DTC and may be cleared with a scan tool without replacing the SDM.

* DTC B0052 56 is a latched DTC. The DTC cannot be cleared with the scan tool. Replacement of the SDM is required.
