Soulds like you have a very similar car to mine. I am repairing a 1.9JTD front damaged.
No power steering = failed Alternator, or Power steering motor.
Traction control light and ABS light will come on after battery is disconnected. Will go off after driving a short distance.
Airbag module must have crash codes removed. Also you will need new seatbelts if they are blocked.
Dont bother with the diagnostics just yet. Fix all the obvious faults and the lights should go off.
front airbag sensor has a yellow connector and sits just behind the bonnet catch, inside the engine bay
Check earth point (black rectangular box bolted to body just behind the battery/ fuse panel, near shock tower) mine was smashed and caused lots of electrical gremlins.
