OBD-II Diagnostic Trouble Code
B0010 — Front Passenger Frontal Stage 1 Deployment Control
B0010 points to the front passenger frontal airbag stage 1 deployment loop, the first-stage squib circuit in the dash-mounted passenger airbag. The restraint control module saw circuit resistance or voltage outside its limits, meaning an open, a short or high resistance. The failure-type byte gives the exact condition, and the meaning can vary by manufacturer.

What this means for truckers
Stop within ~50 miles on a Cummins X15, Detroit DD15, PACCAR MX-13. Driving longer risks damaging adjacent components (turbo housing, head gasket, aftertreatment) and turning a $300 fix into a $3,000 fix.
Before you replace parts — try this first
B0010 is an airbag (SRS) circuit code, most often loose or corroded passenger airbag connector behind the dash. Airbag circuits are not treated like ordinary sensors:
- Treat the airbag as possibly disabled. With an SRS code set, the airbag may not deploy in a crash. Get it diagnosed soon.
- Disconnect the battery and wait before touching anything. Follow the service manual wait time (often 1–10 minutes) so the SRS module reserve power drains.
- Never probe a squib circuit with a test light or ohmmeter. Use the manufacturer's SRS simulator/load tool and a scan tool that reads SRS codes.
- Check the cheap items first. Seat and clockspring connectors under the seat or behind the wheel are common causes after seat or steering work.
- Replace parts only after diagnosis. Some modules must be replaced, not reset, after a deployment.
Symptoms
The airbag lamp stays on and the passenger airbag may be disabled. A passenger airbag status indicator, if fitted, may look wrong. The truck otherwise drives normally. The code often shows up after dash work, a radio, ELD or gauge install, or water getting in under the dash.
Common causes
- CommonLoose or corroded passenger airbag connector behind the dash ($80–$300)
- OccasionalHarness pinched or damaged during dash or aftermarket electronics work ($150–$500)
- OccasionalFaulty passenger airbag module ($450–$1300)
- RareFaulty restraint control module ($350–$1100)
How to fix
Disable the SRS, then inspect and reseat the passenger airbag connector, checking its locking tab and shorting clip
When to use: First check, especially after any dash work
Install an airbag load simulator in place of the passenger module
When to use: To separate a bad module from a wiring problem
Check the harness to the restraint module for opens, shorts and resistance
When to use: When the code stays with the simulator installed
Replace the airbag module or restraint module and clear the code
When to use: Only after the wiring has tested good

Frequently Asked Questions
Can I drive with code B0010?
Drive with caution. B0010 is severity 4 — stop within ~50 miles. Most commercial diesel codes at this severity (turbo, fuel rail, transmission solenoid) can damage adjacent expensive components if left unrepaired. Get to a service location before highway-speed loads.
How much does it cost to fix B0010 on a commercial truck?
Total repair cost ranges $80–$1300 depending on the root cause. The cheapest fix is usually the first one listed below — Loose or corroded passenger airbag connector behind the dash — which is also the most common. On commercial trucks the cost is usually higher than passenger vehicles due to part availability and shop labor rates ($120–185/hour at most truck shops, vs $90–130 at general auto shops). DIY-capable fixes (sensors, hoses, filters) are at the low end; major component replacements (turbo actuator, high-pressure fuel pump, transmission solenoid pack) are at the high end. Always diagnose with a scan tool BEFORE replacing parts — guessing wrong on a $1,500 turbo actuator when the actual issue was a $30 boost hose is a common expensive mistake.
Will B0010 fail a DOT inspection?
B0010 is generally not a direct DOT inspection fail item by itself. Inspectors focus on safety-critical systems (brakes, steering, tires, lights, hours-of-service). However, the check engine light alone can trigger additional inspection scrutiny. Best practice: fix the code and clear it before a planned inspection.
What's the difference between B0010 and related codes?
B0010 is closely related to: B0001 (Driver Frontal Stage 1 Deployment Control), B0020 (Side Airbag Deployment Control), B0028 (Side Curtain Airbag Deployment Control), B0081 (Driver Seat Belt Pretensioner Deployment Control). These codes share the same subsystem (safety) and often appear together. If you see this code, scan for the full code list — fixing the root cause usually clears multiple companion codes at once. If only B0010 is set without the companions, the issue is more isolated.
How do I prevent B0010 from coming back after a repair?
For B0010 (Front Passenger Frontal Stage 1 Deployment Control), prevention centers on the safety system. Don't disconnect the battery without the key off and a 5-minute wait — capacitors can hold airbag-deployment charge. Don't jumper or test airbag circuits with a multimeter (use OEM scan tool). Replace seat belts and connectors that have been involved in a deployment.
