🔧 Code B0010: Passenger Airbag Malfunction – Complete Guide
🚨 Common Symptoms :
- 🚨 Airbag warning light illuminated.
- ⚠️ Risk of non-deployment of the passenger airbag in case of a collision.
⚠️ Possible Causes :
- Faulty passenger airbag (stage 1).
- Wiring issues:
- Damaged harness (short circuit, cut wires).
- Corroded connectors, bent/disconnected pins.
- Cross short circuit between the passenger airbag circuits and another SRS component (e.g., pretensioner, sensor).
- RCM module failure (rare, check last).
🔧 Repair Steps :
🔌 Safety First!
- ⚡ Disconnect the battery and wait 15 minutes before handling the SRS system.
1. Visual Inspection :
- Check the passenger airbag harness (under the seat, steering column).
- Look for exposed wires, burns, or corrosion.
- Inspect the yellow connectors (SRS-specific): clean or replace if oxidized.
2. Continuity/Resistance Test :
- Measure the passenger airbag resistance (compare with manufacturer values).
- Test the circuit for a cross short circuit with other SRS components.
3. Check the RCM :
- Use a professional SRS scanner (e.g., Autel, Delphi) to:
- Read associated codes (e.g., B0011, B0012).
- Check the module’s live data.
4. Replacement :
- If the airbag is faulty → Replace it with an original part.
- If the wiring is damaged → Repair with certified SRS connectors.
📌 Meaning of Code B0010 :
- Description: “Cross short circuit detected between the passenger airbag (stage 1) and another SRS component”.
- RCM Operation:
- The module monitors SRS circuits to prevent accidental deployments.
- A short circuit between two circuits (e.g., airbag + pretensioner) triggers the code.
🚨 Key Points to Remember :
- Never ignore this code: A non-functional airbag endangers occupants.
- Avoid improvised repairs: Use tools and parts suitable for SRS.
- After repair, reset the RCM with a compatible scanner.
⚠️ Warning :
The SRS system is highly sensitive. Incorrect handling may cause accidental airbag deployment. Consult a professional if you are not certified!
