B0044 GMC Code - Driver Frontal Deployment Loop Stage 2 Open
Quick Answer
The driver deployment loop consists of the following components: - A dual-stage inflatable restraint steering wheel module - The inflatable restraint steering wheel module coil - The steering wheel module high circuits for both stages 1 and 2 - The steering wheel module low circuits for both stages 1 and 2 There are 2 shorting bars used within the steering wheel module coil connector. Common causes include Faulty Steering Wheel Module Coil, Steering Wheel Module Coil harness is open or shorted, Steering Wheel Module Coil circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code B0044 GMC Description
- A dual-stage inflatable restraint steering wheel module
- The inflatable restraint steering wheel module coil
- The steering wheel module high circuits for both stages 1 and 2
- The steering wheel module low circuits for both stages 1 and 2
There are 2 shorting bars used within the steering wheel module coil connector. These shorting bars short together both stages of the steering wheel module high circuit and the steering wheel module low circuit when the connector is disconnected. This helps prevent unwanted deployment of the inflator module during servicing. During a frontal crash of sufficient force the inflatable restraint Sensing and Diagnostic Module (SDM) will allow current to flow through the deployment loop. This flow of current will deploy the steering wheel module. The SDM performs continuous diagnostic tests on the deployment loops to check for proper circuit continuity and for shorts to ground or voltage. If a malfunction is detected, a DTC will be stored in memory.
What are the Possible Causes of the DTC B0044 GMC?
- Faulty Steering Wheel Module Coil
- Steering Wheel Module Coil harness is open or shorted
- Steering Wheel Module Coil circuit poor electrical connection
- Faulty Steering Wheel Module

Precautions for SRS “AIR BAG” and “SEAT BELT PRE-TENSIONER” Service
- Never probe the electrical connectors on air bag, side air curtain modules or seat belts.
- Never disassemble or tamper with safety belt buckle/retractor pretensioners, adaptive load limiting retractors, safety belt inflators, or probe the electrical connectors.
- Do not use electrical test equipment to check SRS circuits unless instructed to in this Service Manual.
- Before servicing the SRS, turn ignition switch OFF, disconnect both battery cables and wait at least 3 minutes. For approximately 3 minutes after the cables are removed, it is still possible for the air bag and seat belt pre-tensioner to deploy. Therefore, do not work on any SRS connectors or wires until at least 3 minutes have passed.
Failure to follow this instruction may result in the accidental deployment of these modules, which increases the risk of serious personal injury or death.
