What does it mean?
B1348 is a Body (airbags, seat belts, body electronics) fault code. It indicates: DAB Circuit Short To Ground .
Symptoms
- Airbag warning lamp on and the restraint system disabled
- Driver airbag will not deploy in a crash
- The horn may sound by itself or stop working
- The code sets again on every ignition cycle
- No effect on engine performance
Likely causes
- Squib circuit touching the vehicle body or the steering column casting
- Clockspring ribbon damaged and contacting the column structure
- Wiring pinched between the steering wheel and the shroud during reassembly
- Corrosion in a connector bridging a squib wire to a ground pin
- Airbag module internally shorted to its own housing
- Damage caused during steering column, steering wheel or airbag replacement work
- Restraint control module connector terminal bent onto a ground pin
How to fix it
- Disconnect the battery and wait the specified time before working on the restraint system
- Remove the driver airbag and check both squib wires to ground with the airbag disconnected
- Inspect the clockspring for chafing, cracks and incorrect centring
- Check the connectors at both ends of the circuit for corrosion, debris and bent pins
- Look for wiring pinched under the column shrouds from previous work
- Replace the clockspring or repair the harness where the ground contact is found
- Replace the driver airbag module if the short is internal to it, then clear codes and verify the lamp completes its self-test
