Hey again guys. If I could pick your brains again please if you don't mind!
MOT is rearing its ugly head, and I have two electrical faults I've been looking at today. Major one is that the airbags don't work. Code is 5-2 which from the table in the oracle means "SRS control module, back-up power supply failure -- wiring, SRS control module". What exactly does this mean? Is the module itself faulty internally i.e. a capacitor or similar, or is it a wiring fault to the module? Any ideas would be a great help.
Second fault is that the horn doesn't work, I've traced it through and either there's a wiring fault between relay and switches or the switches in the steering wheel are faulty. Is it possible to even get hold of these?
thanks again.
More trouble!

Re: More trouble!
Try changing the ‘clock spring in the steering wheel, & check the wire wiring under the dash, for the horn
(Got a clock spring here £25 post, if you need it)
Code 52 is the thermal fuse in the Blue box
Simple fix ( but I’ve never done it)
But there are people on here who have

Re: More trouble!
I've replaced the thermal fuse, and its seems to have done the trick, code 52 is gone, now I have code 45. I gather it can only display one fault code at a time...wonder how many ill get!
Could anyone tell me where the centre front crash sensor is please?

Re: More trouble!
Thanks mate. Had a look, dug out the diagram off the forum. I've checked through the wiring thoroughly. From the connectors at the srs module I have the correct resistance all the way through to the crash sensor as well as a good connection to earth.
Is it possible it's an internal module fault?

Re: More trouble!
when tested my crash sensors over the weekend i got omhs of 1180 as per manual
could well be a module fault did you continuity test the module when off

Re: More trouble!
Yeh that's the reading I got as well. I guess I'll take the module apart and check whether I damaged anything when changing the thermal fuse.
What continuity checks can I do with it off?
I'm going to assume these are pretty hard to get hold of if it is knackered?
