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.
