Fault code E 121

Gives this code on start up (E 121) and nothing works besides the horn. I don't have any diagnostic tools for BT so can anyone tell me what this code refers to?

E121 = Steering safety relay deactivated due to incorrect voltage in drive stage or communication error with master processor.

Check the A5 card ( big silver card under the armrest panel.

Unplug all the connectors & reconnect them as a dodgy contact can throw this error code.

Also check the 30 amp blade fuse inside the motor compartment.
