Does anyone know what a fault # 29 is? The airbag light comes on occasionally while driving over very rough road.

Left front sensor - Line resistance too high
Check front sensor at plug connection with ohmmeter .
1. Ohmmeter at terminal 1 and terminal 2
Display: 10 kOhms

2. Ohmmeter at terminal 2 and terminal 3
Display 0...0.5 Ohms
If measured values are within tolerance, renew the control unit; if out of tolerance, renew the front sensor.

Hopefully you only need to clean the contacts...

As usual, thank you very much Jason.
