Passenger Airbag Status Indicator Circuit Range/Performance Problem

The system is checking whether the passenger airbag is ready to deploy or if there's a fault in the circuit, which could mean the airbag won't work in an accident.

The airbag control module monitors the voltage levels and signals from the passenger airbag indicator circuit. If readings are out of range (like below 0.5 volts or over 4.5 volts), it triggers this code.

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. 11. Inspect the airbag indicator light on the dashboard. If it's illuminated or flashing, note the behavior. Decision: Indicator is active; proceed.
2. 22. Check all wiring and connectors related to the passenger airbag and indicator. Look for frayed wires, corrosion, and secure connections. Decision: If wiring is damaged, repair or replace it; retest the system.
3. 33. Measure the voltage at the passenger airbag status indicator circuit. Use a multimeter to ensure it reads between 0.5 to 4.5 volts. Decision: If the voltage is out of range, there’s a circuit issue; continue troubleshooting.
4. 44. Inspect the passenger airbag module and its connectors for damage. Decision: If visible damage is found, replace the module; retest after repair.
5. 55. Clear the fault code and test drive the vehicle to see if the code returns. If it does, further investigation of the airbag control module may be necessary.

• Faulty passenger airbag status indicator
• Wiring issues to the airbag module
• Corroded connectors under the passenger seat
• Malfunctioning airbag control module
