DTC: 0x0F = 15

condition2 : 0x5A

DTC: 0x02 = 2

15 Driver side front side impact sensor

2 Airbag control unit supply voltage

Anyways i cleared them & they stayed clear.

Apparently the wife had driven the ca rover a kerb at lowish speed & then the airbag light came on.

Clean and the connector under the seat and cable tie it together tightly, I had the same problem after moving my passenger seat to fit a large mate in the back.
