SRS Fault on Freelander 1

The SRS warning light has been constantly on for the 4 months I have owned my 2000 Freelander 1 V6. I hoped it would be something simple like the under-seat seat belt pre-tensioner connections. I renewed the under seat connectors and took the car to an independent LR service centre to (hopefully) have the fault cleared. Unfortunately, the fault download showed:
1. Airbag control unit fault
2. (Intermittent) Airbag control unit fault
3. (Intermittent) Battery voltage fault

These faults could not be cleared.

Any advice on a logical fault finding process would be appreciated.

That points to the airbag control unit. Sometimes the wiring for it can suffer from bad connections.

I've read that the SRS ECU is a one use item. I've also seen web sites offering to clear the crash code data. I've also seen quite a few used SRS ECUs for sale.

If I fit a used SRS ECU from another vehicle that does not have any recorded crash data, will it work OK?

If it's from a similar year FL1, then yes it should work ok. Be warned that getting to the SRS ECU is a bugger as it's under dash.
