The B0103 code on your 2020 Chevrolet Silverado indicates a fault in the right front side airbag circuit. This code affects your Silverado's SRS system, signaling a potential problem with the passenger side airbag that could affect deployment during a side-impact collision.
Understanding B0103 on Chevrolet Silverado
Code B0103 is the passenger side counterpart to B0102. The sensing and diagnostic module (SDM) monitors the right front side airbag circuit continuously. When a fault is detected - whether open circuit, short circuit, or resistance out of range - B0103 is set and the airbag light illuminates.
Common Symptoms
- Service Airbag message or light
- No drivability symptoms
- Passenger side airbag may not deploy
- May accompany other SRS codes
Primary Causes
- Wiring damage in passenger seat
- Corroded side airbag connector
- Faulty passenger side airbag module
- Seat track sensor issue
- Impact damage to wiring
- Objects under seat damaging wiring
Diagnostic Procedure for 2020 Silverado
SAFETY: Disable SRS before work. Using a GM scan tool, access SRS diagnostic data for the right front side impact sensor/airbag circuit. Inspect wiring through the passenger seat carefully. Check side airbag connector in seat bolster. Verify no objects under seat are contacting wiring. Check for prior collision damage that may have affected components.
Repair Solutions
Repair damaged wiring using proper automotive techniques. Clean corroded connectors and apply dielectric grease. Replace faulty side airbag module following GM procedures. Ensure proper wiring routing through seat. Clear codes with GM scan tool and verify circuit status returns to normal.
