Hi
I've suddenly developed a problem with my X-Type 2005 2.0l D estate.
The radio/cd stopped working.
I found fuse f43 blown, f44 ok.
Replaced f43, blown again.
I stripped out the radio/cd and checked things as per a previous post.
I found a short to ground on the 0v side of f43 and the same on the yellow/green wire on the head.
Now I've stripped everything out including instrument cluster, glove box etc but I'm finding it difficult to see exactly where the yellow/green cable goes.
Are there any likely places where this cable could possibly short?
I have multimeter, wiring diagram in workshop manual etc.
Any hlp would be appreciated.
Brad

Check R2 (relay) in the passenger junction box (fig 01.4 in the electrical drawings)
sounds to me like the coil has shorted.

 

Thanks for your response ... I'll check R2 out as soon as I can.
The cable I mentioned (yellow/green) doesn't appear to go anywhere apart from the fuse F43 and the radio/cd unit, so it looks like the cable itself is grounding.
I'll let you know how I get on with the relay.
Brad

 

Hi again.

Strange, there is no relay R2 fitted in the passenger side fusebox.

Brad

 

Further developments ..... I pulled the multi-connector on the passenger side fusebox (the one containing the yellow/green cable) and found that there is continuity in the cable between the fusebox end and the radio/cd connector, BUT both ends show as grounded.
I assume that somewhere along the length of the yellow/green cable it is contacting earth. I checked the pin on the fusebox where the yellow/green cable fits and all seems well (not grounded), so I rule the fusebox out.
I fully understand why relay R2 should be suspect, but I'm sure the problem now lies in the cable itself.
How can I find exactly where, in the cable, it is earthing?
Brad

 

Brad.
Ok R2 is for the Towing package and rear power (cigar lighter).

now as for the rest of the yellow green wire.
bottom of the LH A pillar where the Passenger`s (UK) left foot rests is a BLue 15 way connector pin 1 is the cable.
then in the head unit (you have checked)
now the wire runs down along the bottom of the passenger (UK) doors to a Grey (pin10) and blue (pin2) under the rear seat (for factory NAV and Telephone )
then into the trunk/boot behind the Passenger (UK) tail light. (check here first the factory usually tucks the wires up out of the way and can rub )

hope this helps

 

Hi
I've not found any yellow/green wire anywhere in the passenger side tail lamp area, BUT I've found the blue multi-connector you mentioned (pin 2) under the rear seat cushion and the yellow/green wire there is also grounded !!
So I assume the cable could be earthed anywhere along where you said.

 

ok
do me a favor. unplug the blue plug passenger side foot area
check for continuity to ground on the male side pins 1 and 16,
this will tell us which way to look from there.
pin 1 goes to the head unit pin 16 goes to the plug under the rear seat.

 

I tested pins 1 and 16 as you mentioned ... pin 1 = yellow/green is still grounded, pin 16 = yellow/blue appears okay.
As an interest, I stripped away the area around the floor/inner sill rear passenger and found the yellow/green cable ... I cut this and tested again. Rear portion is okay, forward of this is grounded.
I did the same with the front passenger floor area. Rear section is okay, front is grounded.
Therefore, the short must be in the cable between the A frame, the blue connector at the fusebox and the head connector (the awkward bit).

 

Good we are getting closer.
Remove the plug from the back of the head unit also the blue plug at the `A` pillar

now test at the head unit plug pin 2 see if you still have ground.
this will tell us if its the cable or a short in the head unit.

If it is the cable just cut the bad cable leaving 2-3 inches at both plugs and splice in a new one.

 

Hi
Yes, I tested the yellow/green cable while is was disconnected at the fusebox and the head, and it was still short to ground.
I think your suggestion of splicing a new cable between each plug end makes every sense as it would be very difficult to find the exact place under the dashboard where it is shorting out even if I took the passenger airbag out. At least it would only be one cable with just 2 connections.
I'll let you know how I progress if that is okay.
Many thanks again for all your help.
Brad

 

Sounds good.
personally I would solder and heat shrink the connections.
but a good crimp connector will do.

I would still take a look where the cable runs as we don`t know what else could be damaged or any potential future failure.

 

I would have soldered and heat-shrinked the cable anyway ... proper job !
Good point you mentioned about checking the cable run anyway, for the future.
I've to take the passenger air bag out in any case, so I should be able to see more of the yellow/green cable with it out of the way. Incidentally, I've just ordered a length of new cable with the correct colours ( I like to keep things tidy).

 

You may be able to remove the Glove box save disturbing the air bag and get access there.
Keep forgetting you are in the UK, in our cars here that loom goes over the steering column.

 

I'd taken the glove box off a few days ago ... the wiring harness on mine leads from passenger side (our nearside, left) fusebox, up the A frame, along the back of the passenger air bag and re-emerges on the left of the console containing the radio/cd and AC units. 4ft of cable at the most. I'll wire the new cable and reconnect the yellow/green cable running under the rear seat.
I'll make a start when the rain stops (if ever !).

 

Did you get to the loom? how does it look?
hopefully not that bad.

 

Hi
I've just managed to get working on the car now the rain has stopped!
Update:
I found the yellow/green cable in the harness going up the A frame (to the instrument cluster), I cut it and tested continuity = cable to instruments is okay.
It removed trim around the bottom of A frame and found a whole load of connectors behind the bonnet (hood~) release lever. I found the yellow/green cable on the blue connector and unplugged it. Now there is no grounding anywhere on the yellow/green cable. I then tested appropriate pin in the blue socket and it is earthed. It looks very difficult to get to the other side of the socket to see where the pin is connected.
I'm tempted to cut the yellow/green cable near the blue plug.

 

I assume the blue connector behind the bonnet/hood release lever is CA203 in the wiring diagram. Tested pin 1 = grounded and pin 16 = is okay and there is good continuity between pin16 and the radio/cd head connector.

 

OOOoooops, connector is CA230 NOT CA203.
