B0034
DTC B0034
CIRCUIT DESCRIPTION
The inflatable restraint sensing and diagnostic module (SDM) contains a sensing device which converts vehicle velocity changes to an electrical signal. The SDM processes the generated electrical signals and compares them to values stored in memory. When the generated signals exceed the stored value, the SDM performs additional signal processing and compares the generated signals to signals stored in memory. When two of the generated signals exceed the stored values, the SDM causes current to flow through the inflatable restraint side impact module - LF, deploying the side impact module - LF and causing Diagnostic Trouble Code (DTC) B0034 to set.
DTC DESCRIPTOR
This diagnostic procedure supports the following DTC.
DTC B0034 Side Airbag Deployment Commanded
CONDITIONS FOR RUNNING THE DTC
Ignition 1 voltage is within the normal operating voltage range.
CONDITIONS FOR SETTING THE DTC
The DTC will set when the SDM detects a side impact crash of sufficient force to warrant deployment of the side impact module - LF.
ACTION TAKEN WHEN THE DTC SETS
- The SDM turns the AIR BAG indicator ON.
- The SDM records crash data.
CONDITIONS FOR CLEARING THE DTC
The SDM has the ability to command three side impact module deployments. After that, the SDM must be replaced.
