Passenger Airbag Squib 1 Circuit Open
The control module detected an issue with the passenger airbag squib circuit.
Heads up: this code wasn't in our hand-written library yet, so DiagCoach AI built this page on the fly. Double-check critical specs against service info before condemning parts.
What it means (plain English)
This means that the passenger airbag's electrical circuit is open, which means the airbag is not ready to deploy in an accident because it can't send or receive signals properly.
What the computer is actually seeing
The airbag control module monitors the resistance of the squib circuit. A normal range is typically around 2 to 30 ohms for the airbag circuit. When the resistance is infinite (open circuit), it triggers the B0026 code.
What a healthy reading looks like
Resistance must be between 2 to 30 ohms; anything outside this indicates a problem.
Guided diagnostic — the DiagCoach way
Don't just throw parts at it. Walk through these in order — each step tells you whether to keep going or stop and fix what you found.
- 11. Check the wiring and connectors between the airbag module and the passenger airbag. Look for any signs of damage, corrosion, or disconnection.
- 22. If wiring is intact, use a multimeter to measure the resistance across the airbag squib terminals. Ensure the resistance is between 2 to 30 ohms.
- 33. If resistance is open or very high, inspect the squib itself for damage. If squib looks good, consider swapping the airbag module for testing purposes.
- 44. Clear the code and do a test drive to see if it returns. If it does, replace the airbag or module based on tests.
Common causes
- Broken wire in the squib circuit
- Corroded connector terminals
- Faulty airbag module
- Dislodged or damaged airbag connector
- Aftermarket modifications or installations affecting the circuit

Will this code come back after repairs?
If the electrical circuit is properly repaired and the airbag module is functioning, the code should not return.
Why does this code show up with other codes?
They are often related to other airbag system faults that share components or wiring.
