Hello,

Does anyone have access to the wiring diagram for the climate control of a 2013 model year XF?

I have an issue with the climate control module (a.k.a. Automatic Temperature Control module) not having power on its supply wire. If it connect a wire from the cigar lighter socket to the supply wire the climate control starts working. All fuses appear good (lots of testing with a voltmeter).

The wiring is similar to (but annoying different from) the wiring diagram here (named 2012, copyright 2011):
http://www.jagrepair.com/images/Elec...20X250Comp.pdf

The power supply wire in my case is Brown and Red, rather then Red as shown on page 78 of the above PDF at connector terminal C2H101A/1. It doesn't come from the central junction box and seems to head to the engine compartment from a connector near the central junction box. There is no fuse 25 (nor spades in the socket) in the central junction box. Fuse 23 is "Air Conditioning" in the owner's manual, which has 12V both sides (this is the auto headlights sunlight sensor fuse number in the 2011/12 wiring diagram).

Any help greatly appreciated,

James

 

Here you go.

It does look a bit different, doesn't it.

 

Thank you very much u102768, that shows that the supply does just come from the central junction box but on a different connector from the previous version (C3BP01E rather than C3BP01C). Are you also able to post the central junction box pages (like pages 85 to 95 in the 2012 version (101 to 111 of PDF)) so that I can list out the colours of the wires on C3BP01E to work out which connector it is on the junction box? I've found one Brown/Red wire but I'm not sure it's the right one.

My car is RHD, I assume that on a LHD car, the climate control module is directly above the central junction box on the right hand side, rather than on the left hand side as on my car. I think the connectors under the central junction box may just be to an "extension loom" from the right to the left of the car, meaning the connectors aren't marked on the wiring diagram.

I'd love to work out where connector C12-B marked on the Brown/Red wire is. Somewhere the loom from C2H101A splits at C12-A and C12-B, having gone directly to the In-vehicle Temperature Sensor (and maybe a few other places) on the way.

I'm trying to fill in the second sheet on the attached Excel workbook.

Thanks again,

James

 

Here you go. It took me a little while to confirm what you wanted because the 2012 document on Jagrepair is missing over 40 pages compared with the proper manual so the page numbers don't match.

C12-B is listed as 'Base of right A pillar' and it is green.

 

Thanks again u102768,

It's looks like this is another symptom of this issue with water ingress from the windscreen washer pump:
https://garagewire.co.uk/news/compan...-junction-box/

Connector C3BP01E is the top left connector (grey) on the CJB. I unplugged it and found that pin 20 had completely corroded away (pin 19 looks a bit corroded but the others look OK. The washer pump is pin 7 in the same connector.

Does this fault mean the water is travelling inside the insulation of the washer pump wire? The wire goes upwards to the CJB connector.

I'll just have to solder a wire from fused site of the back of fuse 22 to the back of the pin on the wiring loom connector. I don't fancy removing the CJB to solder new pins in as others have (rather than paying Jaguar £1200+ to replace the CJB, pump and loom and reprogram the CJB to match the car).

I guess I should also replace the washer pump to stop the water ingress problem damaging anything else. Others having suggested putting some kind of connector/splice in the wire from the pump to stop water travelling up it. Can anyone suggest what would be best for that?

Thanks,

James
