What does it mean?
B1347 is a Body (airbags, seat belts, body electronics) fault code. It indicates: DAB Circuit Resistance Is Low .
Symptoms
- Airbag warning lamp stays on from key-on
- Driver airbag deactivated, correct deployment cannot be guaranteed
- Horn or steering wheel switches may also misbehave
- The fault repeats immediately after clearing
- The vehicle otherwise drives completely normally
Likely causes
- Partial short between the two squib wires, usually inside the clockspring
- Clockspring ribbon crushed or chafed because of incorrect installation
- Airbag connector terminals bridged by corrosion or debris
- Internal fault in the driver airbag inflator circuit
- Wiring pinched during steering wheel or column shroud reassembly
- Moisture in the connector after a leaking windscreen or door seal
- Restraint control module fault
How to fix it
- Disconnect the battery and observe the specified waiting period before touching the airbag
- Remove the driver airbag and inspect both the airbag connector and the clockspring connector for corrosion and debris
- Verify the clockspring is properly centred and that its ribbon is not pinched under the shroud
- Use the correct airbag simulator or load tool to establish whether the low resistance is in the airbag or in the circuit
- Check the restraint module connector for bridged or bent pins
- Replace the clockspring when the low resistance follows the wiring side
- Replace the driver airbag module when the low resistance follows the airbag, then clear codes and confirm the self-test passes
