Seat Belt Pretensioner Circuit Failure (Right Front)

Indicates there’s a problem with the right front seat belt pretensioner 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 right front seat belt pretensioner is either faulty or not getting the signal it needs from the airbag system, which tightens the seat belt during a crash to keep the occupant secure.

What the computer is actually seeing

The airbag control module monitors the pretensioner circuit for continuity and proper voltage. If it detects an open circuit, short to ground, or short to power, it sets the B1944 code.

What a healthy reading looks like

The pretensioner circuit should show around 2-3 ohms of resistance when tested; the signal voltage should be near battery voltage (12V) when activated and close to 0V when not activitated.
