2010 clio gt airbag problem?

my cars had an accident, so i replaced the dash, passenger & drivers airbags, airbag computer and 2nd hand seatbelt pre tentioners (when pre tentioners came the plugs were different so i was told to cut the plugs off and solder the wires together). now after taking the car to renault to have plugged in to reset everything, it has come back with the following.

df074 passenger front airbag circuit 2.
df177 drivers side rear inertia reel circuit.
df178 passenger side rear inertia reel circuit.
df240 drivers lap strap/seat airbag circuit.
df241 passengers lap strap/seat airbag circuit.

can you give me any info on this and is there a way of by passing the seat belt pretioners, all new parts were fitted whilst the battery was disconnected, once re connected all parts seemed fine. car was then towed for reset.
