Passenger Side Airbag Circuit Short to Ground

A short in the passenger airbag circuit has been detected.

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 has found a problem with the wiring for the passenger airbag; it might be shorting out, which could prevent the airbag from deploying properly in a crash.

What the computer is actually seeing

The airbag control module detects a voltage drop or continuous low signal from the passenger airbag circuit when it should see a normal resistance value.

What a healthy reading looks like

When the circuit is functioning normally, expected resistance should be around 2-10 ohms between the airbag module and the passenger airbag.

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.

  1. 1Check the passenger airbag connectors for loose or corroded pins.
  2. 2Inspect the wiring harness between the airbag module and the passenger airbag for physical damage.
  3. 3Measure the resistance of the airbag circuit: check between 2-10 ohms.
  4. 4Ensure the passenger seat's positioning isn't pinching any wires under the seat.

Common causes

  • Damaged wiring harness
  • Faulty passenger airbag
  • Corroded connectors
  • Aftermarket modifications or installations
  • Seat movement affecting wire integrity

Typical repair cost

$$$

Will this code come back after clearing it?

Yes, if the underlying issue is not fixed, the code will return.

Why does this code sometimes pair with others?

Multiple codes can indicate issues in the airbag system, especially if wiring damage affects multiple circuits.
