Passenger Airbag Status Indicator Circuit Short to Ground
There is a short circuit in the passenger airbag status indicator 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 passenger airbag status indicator is wired to the airbag module, and when the light is on, it means there's a problem, typically a wire or connector issue causing it to short out instead of just telling you if the airbag is ready or not.
What the computer is actually seeing
The airbag control module detects a voltage drop in the passenger airbag status indicator circuit due to a short to ground. Normally, this circuit should report the status of the airbag, receiving around 2-5 volts when operating correctly.
What a healthy reading looks like
The voltage at the passenger airbag status indicator circuit should be between 2 and 5 volts with the ignition on and not illuminated when the airbag is functioning properly.
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 related to the passenger airbag indicator for visible damage, wear, or corrosion. Decision: Is there damage? If yes, repair or replace the afflicted wiring/connectors. If no, proceed to step 2.
- 22. Use a multimeter to check the voltage at the passenger airbag status indicator circuit with the ignition on. You should see 2-5 volts. Decision: Do you see the correct voltage? If yes, the issue may be in the airbag module. If no, there is likely a short to ground.
- 33. Check for shorts to ground in the wiring back to the airbag control module by performing a continuity test. Look for connections that are improperly grounded. Decision: Is there a short? If yes, isolate and repair the wiring. If no, replace the airbag control module.
Common causes
- Damaged wiring harness
- Corroded connector terminals
- Faulty airbag module

Frequently asked questions
Is it safe to drive with this code?
It's advisable to fix this soon as it may affect airbag functionality in a crash.
Will this problem come back after repair?
If the wiring and connectors are properly fixed, it shouldn't return unless there's a new issue.
Why does B1997 pair with B1996?
B1996 also indicates airbag circuit issues, so they often occur together when there's a wiring problem.
