Airbag and Seatbelt warning light

Posted Today, 01:42 PM
Hi all I've been searching deep corners of the internet and have had no luck for this issue.
HTML Code:
10 plate focus 1.6 zetec (100)
I was driving along one day no problems and have had no problems at all before. dropped of my mate at his house and grabbed something out of my boot at the same time, then pulled off and about 20 yards later both the airbag and seatbelt warning light came on...

over the next 2-4 days it was intermittent, then it became permanent for the last 2 weeks to date. When intermittent it sometimes was not on at all, other times it came on part way through the (short) journey, or it was on straight away and turning the engine off then back on didn't get rid of it.

I did the ford built in diagnostics check I've borrowed one of my mates cheap as chips bluetooth OBD reader and found these codes:-

HTML Code:
Obd
U1900 - CAN Communication Bus Fault
U2023 Abnormal message from PCM

Ford onboard test:
Dtc #01 D900
I tried to reset them but couldn't.
the only other thing I have tried is disconnecting the battery for the car for about an hour or so (turning it off the on again idea)

does anyone know what it could be?

I would like to repair it myself (I'm great with repairing electronic side of things, it's part of my job).

Cheers,

Gee.

Make sure seat electrical connector under the seat is in order.

thanks,

ok just pulled those connectors out, looked at the crimping and stuff and they seem fine sprayed them with some contact cleaner and still getting the lights...

Would you (or someone) know the Ohm values of the connectors? so I can test for a break in them (I won't use continuity encase that is enough to set off the airbag or do other nasty stuff).

Cheers,

Gee
