Hi all
Been pottering away with reinstalling all the headlining and interior, car was driven a few times but now has thrown a wobbly.
When connecting the car battery the nav screen comes on for a second or so but there is no power to the start stop button, no lights can be switched on but the windows work and the seats are in 'inch' mode.
Had the auto electrician come out and the problem is that as the ignition will not turn to position 2 so cannot communicate with much either. There appeared to be a number of DTC codes on his scanner.
Key is transmitting, battery is all good, have done the leads off, negative lead off and touched to connected positive and no joy.
Suspect that the car may be thinking it has been stolen and has immobilised. I even went hunting for an inertia switch but couldn't really zone in on it, thought it was in or near the passenger side fuse box but no joy.
Electrician is finding power at the fuse box in the engine bay and has checked the fuses which all appear sound.
Anyone any ideas?
Thanks for any response in advance

 

All or most computers need to be reset. Car was too long without a battery. Dealer or a Mongoose SDD reset.

 

I've not yet heard of that. My son's XKR sat over a year with no battery. It started up fine afterwards.
I guess it is possible that SDD could wake something up though. The first step on SDD is "Place ignition to position 2 (ON). Is ignition in position 2 (ON)?"

 

Yes his situation is unorthodox, so now maybe the time to join the + and - leads together, without the battery involved. Even the owners manual says not to let the car go without a battery for more than 72 hours. Your son was luckier than most.

 

Thanks for the reply as I said the ignition will not switch on at all, there is no effect when pressed in any manner
I am trying to figure out how any scanner could be set up as the ignition on off cycle can’t be completed to allow the car to be programmed

i have also tried touching the leads together, as well as leaving them off as well as touching negative to positive whilst positive is still connected All to no avail

 

as I said there is no power at all to the start stop button so it will not activate position 2

 

Voltage off of the battery? Clean the battery contacts! Clean all grounding wires. The scanner goes in through the OBD2, where there is some juice to probably get a response.

 

The battery is at 13 plus volts, if you mean the ODB port that is on the drivers side under the dash. Not sure about what you mean about the wires through the glove box? Can you explain further please cheers

 

It says that after 72 hours the radio preset channels will have to be reset. That's it.

 

Mentioning the wires in the glove box was only for the sound system i think.. My Mongoose SDD only goes thru the OBD2 plug. I picked up the Chinese copy because my car arrived last summer with a dying battery, creating a reset to the seats computer. I am keeping the Mongoose for future problems with all those onboard computers.

 

Switching the + and - will get the same, no ignition response. (trying all possibilities)...

 

Central junction box, check under rear seats
was there water spilled or intrusion into the interior?

also make sure your battery was tested for amperage not just voltage.

 

No water spilled, battery is all good according to the auto electrician.
You mention the junction box? do you mean unplug it and plug back in?

 

there is a response from the scanner but it cannot communicate as the ignition cannot be energised to follow the steps to go any further.
As I said originally i suspect its immobilised and am wondering what a next step would be to somehow get power to actually recode or communicate with the modules

 

Junction box aka body control module, is underneath the rear seats and
has alot of parts to it. It controls all power to the car. I suggest you go to a jag specialist
that knows where and what this is.

 

problem is there is no jag specialist where i live,
i know where the box is because i have had the interior out whilst i was replacing all the linings, its the only way to remove some panels to allow the complete interior to be removed
Car has been driven quite a few times since then with no problems
i suppose i could call a specialist on the north island and remove and send on to them for inspection

 

That's why I said the above, in response to a different member's post.

 

Try pressing the start button BEFORE you step on the brake pedal.

If you inadvertently pump the brake pedal before you press the start button, your brake pedal will be high and hard as a rock and might not make contact the starter interlock switch. In that case. you would need to stand on the brake pedal as hard as you can with both feet after you press and hold the start button.

 

Which 2007 Smartkey do you have?

2007 model year X150 cars were equipped with "single channel" Smartkey fobs through VIN B12815 and "multichannel" fobs thereafter. Those single and multi-channel fobs are not interchangeable. Read this old 2014 thread in its entirety, and Post #61 in particular:
https://www.jaguarforums.com/forum/x...cement-117974/

When buying a second fob, make sure that you have a written guarantee that it is fully refundable within 60 days from the date of receipt, including return shipping with no restocking fees. Pay for it with a credit card, to better protect your rights. You need 60 days to have enough time to get a Jaguar dealer or indie to program it and get the emergency key laser cut.

Both Smartkey fobs will have to be present together with the car for them to be programmed to be car. It is not a simple process and requires the Jaguar software to do it.

Good Luck!

Stuart

 

Yep been doing that as I am only wanting it to go to position 2
I have no ignition response at all, no lights, wipers anything
