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.
This diagnostic procedure supports the following DTC.
DTC B0034 Side Airbag Deployment Commanded
Ignition 1 voltage is within the normal operating voltage range.
The DTC will set when the SDM detects a side impact crash of sufficient force to warrant deployment of the side impact module - LF.
• | The SDM turns the AIR BAG indicator ON. |
• | The SDM records crash data. |
The SDM has the ability to command three side impact module deployments. After that, the SDM must be replaced.
Step | Action | Yes | No |
---|---|---|---|
1 | Did you perform the Diagnostic System Check - Vehicle? | Go to Step 2 | Go to Diagnostic System Check - Vehicle in Vehicle DTC Information |

Does the vehicle exhibit signs of side impact module - LF deployment? | Go to Step 5 | Go to Step 3 |
3 | Inspect the side of the vehicle and undercarriage for signs of impact/collision. Does the vehicle show any signs of impact/collision? | Go to Step 5 | Go to Step 4 |
4 | Replace the SDM. Refer to Control Module References in Computer/Integrating Systems for replacement, setup and programming. Did you complete the replacement? | Go to Step 6 | -- |
