Any body have an idea where i should look for a resolution to the above error.
all was good when we arrived at a site recently but when we set off back home the above error came up, i have connected my computer to the Cab but i can not clear the fault, anyone know where the ECU for the air bag's is so i can trace the wiring see if that is a wiring fault or an ECU fault.

The computer does not let you know which air bag is at fault.

This shows where it is but when ours said it couldn’t communicate it was because the whole unit was deceased and needed renewal.

I did hear about the seatbelt wiring getting trapped under the front seats when turned round when being used on site, why it should give an airbag warning I’m not sure.

It’s because the seat belt pretensioners are controlled by the air bag ecu. Any change to the circuitry affects the ecu
