Front Seat Cushion Deployment Command Circuit Low
Low voltage detected in the front seat cushion deployment 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)
The airbag system can't properly check the seat's deployment circuit because it sees a voltage lower than 2 volts, indicating a possible fault in wiring or connections.
What the computer is actually seeing
The airbag control module is monitoring the voltage in the seat cushion deployment circuit. It expects a voltage between 2 to 5 volts during a diagnostic check. A reading below 2 volts triggers the B0065 code.
What a healthy reading looks like
Expected voltage in the deployment circuit is between 2 to 5 volts.
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. Inspect the wiring and connectors for damage or corrosion under the seat. Check for loose connections.
- 22. Measure the voltage at the airbag module connector while the ignition is ON (engine off). Expect 2-5 volts. If low, go to step 3.
- 33. Check the circuit integrity from the airbag module to the seat cushion connector. Repair any damaged wiring found.
- 44. If wiring is intact but voltage is still low, test or replace the seat occupancy sensor module.
Common causes
- Damaged wiring in the seat cushion circuit
- Corroded connectors
- Faulty seat occupation sensor module
Typical repair cost
$$$

Frequently asked questions
Is it safe to drive with this code present?
It's not recommended to drive with a B0065 code, as the airbag system may not deploy in a crash.
Will this code come back after I clear it?
If the underlying issue is not fixed, the code will likely return after clearing and cycling the ignition.
Why does this code pair with B0051?
B0051 indicates a fault in the driver's airbag, and both codes can stem from similar wiring issues or faults in the airbag system.
