Hi,

I've recently acquired an 2010 L322 Autobiography.

There are a couple of things to sort on it, one of them is the rear electric seats. They dont work (either recline or lumbar adjustment), the switch in the back to move the front passenger seat doesnt work (but that front passenger seat works fine from its own switches) and the rear seat heat / chill does not work, although the dials do light up.

The rear window isolation switch was not on (confirmed by being able to lower the rear windows). I've checked the plugs in the compartments in the rear seat bases and they are intact, dry & uncontaminated). I've either checked all relevant fuses or they power something else which is working fine.

I've seen a couple of reports online from people experiencing the same issue but unfortunately no solutions.

Has anyone had this issue, been able to fix it and can point me in the right direction of what to check next please?

Thanks & best regards
Richard

Hi Richard, I don’t have the electric seats but have a similar problem which may be the same issue you are having with no lower going to the rear seats. My issue is the rear seat heater buttons don’t light up and the seats don’t heat, however on two occasions in the last 3 years they have all of sudden worked but went off again after about an hour. I think the rear seats are wired through the same fuse that lights up the gear selector panel ie the one that lights up red when in park and changes to orange when on other gears. When my seats worked on the 2 occasions that panel lit up whereas usually the gear selector lights never work. I’m guessing my problem is a dodgy earth somewhere and you may have the same issue.

Does your gear selector panel light up or not ? Failing that I wonder if it’s the battery monitoring system chopping power to the rear seats as it’s not an essential item. Hope this helps and you manage to find a fix.

Please make sure this is not turned on

Sadly it's not just the isolation switch being on

Thanks though & best regards

Hi, do you have the Gap IID tool ? If so you could check they are classed as fitted in the car CCF file. That would be one way for someone to disable them. If in the file it says Not Fitted then that could be the issue. We got a 3.6 for mu son in law that had deplorable side steps fitted but didn’t work, the CCF file showed not fitted so we changed it to fitted and they worked straight away if my memory serves me correctly.

Hi,

I dont have the IID tool unfortunately.

I actually emailed GAP, to ask if the seats can be disabled by IID. The very prompt reply said "If LR did implement these in the ccf then yes. No one tried these thus cannot confirm.". I can't (yet) find a list of the values available in a ccf.

If you have an IID might you be able to be good enough to have a look to see if there's values for rear seat electric adjustment and heat / chill please? Being available as an option, using some of the same equipment (front seat modules) you'd assume that there must be something in there.

As the seats weren't working from day 1 I'll be expecting the dealer to cover the cost of getting them sorted out (unless it's done as part of the diagnostics check I've got it booked in for) so I've yet to decide if it's worth investing in an IID.

Thanks & best regards
Richard

Hi Richard, I’m not too sure the GAP tool will be able to access your CCF file or if it does it may not allow you to change it. They are VIN locked but I can check for you possibly tomorrow, both my son in law and I have one each so I will check mine in his car to see if I can access his CFF file or someone on her may be able to confirm if it’s possible or not. If it’s possible I don’t mind you using mine to check, I’m just off the A1 about 3 miles north of the metro centre.

Sorry just realised what you were asking , it definitely has a CCF option for rear climatic seats !

Hi,

Excellent, thanks!

Is there any indication if in addition to the rear climatic seats CCF option there is also one for rear electric seats?

Best regards
Richard

Not too sure about rear electric seats, I would have to check tomorrow and let you know. When I was hunting information regarding my rear seats I noticed how the power goes through various electrical circuits, switches, relays and earthing points before it hits the rear seat heaters. I’m sure my issue is an earth point along the circuit as they did work on two occasions so definitely an electrical issue that no one else seems to have had as no one seemed to have suffered the same issue which is surprising.

A unique problem on any Land Rover is certainly, well, unique! haha

I can recommend an auto electrician in Sacriston (DH7), they've apparently got dealer level diagnostics kit for LRs.... Abbey Auto Electrics.

If I've understood the wiring diagram correctly there's only one earth for the seat heaters, at connector C1972-1 although it passes through other connectors on the way (including one where left & right side earths are combined). Have you tried adding a temporary earth from one of the heater plugs, to see if that side starts working?

There are workshop manuals online which include wiring diagrams. What I havent found though are the connector locations for 2010 vehicles. There's a link in the wiki for the 'electrical library' but its for the earliest vehicles. Some of the connector locations are listed but several of the seat ones are not.

Best regards
Richard

Hi, there is indeed two options for the rear electric seats in the CCF files, rear seat recline movement and rear seat lumbar movement. Obviously they say not fitted on my car but would be interesting if it says the same for you, can’t imagine anyone would turn them off with a diagnostics tool though. Hope this helps.

Excellent, thanks for the info.

It's booked into an independent specialist but not till the 9th. I'll make sure to ask them to check if the electric / climate seat entries are down as fitted.

The only scenarios I can see are either that a previous owner has got sick of his kids fiddling with them and wanted to disable them (*), whilst being able to open the windows. Or, that the front seat modules have been changed in the past & that they need to be told that there are rear electric / climate seats too. A long-shot I know but them being broken would seem to be both the seat modules being partly broken, in exactly the same way each.

* = I'd have just carried a long stick in the car

Hi RJPotts. I have exactly the same issue as you describe in a 2010 Autobiography. Did you get an answer as to why the electric rear seats do not work, no climate control working either, yet the climate control lights up on the door.

I have checked cables and confirmed the fuses also control drivers seat which works, so ruled it out. Any help much appreciated.
