| 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. The SDM must therefore be replaced using the 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. This DTC cannot be erased with the scan tool. The SDM must be replaced.
