Hi all, I've had the battery on and off the car a few times lately as part of my recommissioning tasks. I now have a multitude of warnings on the dash with the only code I'm getting being p1000. Here's what's flagged or not working. Abs light, cruise not available, dsc not available. Speedometer not working, but it was intermittently. Radio requesting code then saying please wait along with sat nav not working. Also after initial start up a gearbox fault warning appears. Car drives fine initially then as you move the shift to park it lurches horribly through reverse into park. Any ideas gratefully recieved.

 

Is the battery fully charged? Have you tried a hard reset?

 

Hi , yes battery is ok. I did a hard reset prior to taking her out for a run yesterday.
All the mentioned issues which were cleared have reappeared. I will try another reset tomorrow but wondered if any one had any other ideas. None of these problems were here when i got the car. I will check battery again.
Thankyou for your assistance.

 

All those sound like C codes so you need to forget P codes for a while.

 

I've just nipped to the lock up and done a hard reset. No change.battery read 12.83v on the trickle charger and 14.1v with engine running. I used a cheap basic scan tool on it earlier and it flagged up 3 dtc. When I tried to read them it asked me to select manufacturer which I did, and the 3 codes did not show but were replac3d by p1000. Apart from the gearbox clunk when going into park she drives perfect.

 

Keep in mind multiple codes do not necessarily mean multiple problems which is a good thing. However you really can't do any further troubleshooting till you are able to read the codes which I'm sure you already know. Let us know what you find and good luck.

 

Plan of attack is to buy a better scanner and drive it more.

 

It will not cost anything to check / clean contacts on the main junction box in the trunk that may be robbing components of their proper voltage from a battery that is in excellent shape.

Check the gearbox oil level .....first step with any gearbox problem.

 

Hi, thanks for the help. I pulled every fuse on the car over the weekend. Will clean the mega fuse connections in the boot and will also check gearbox oil which is due a change anyway.👍

 

P1000 is normal after battery off. (If all is well it'll change to P1111 but all obviously isn't well.)

The other problems are probably not emissions ones so a basic tool won't show them. They'll be B, C, or U codes and from the modules other than the one a basic tool supports.

 

Thats great info. Thanks.
I am getting a better code reader which you show is a good idea.

 

In addition to the fuse connections, if you have not already done so, there are electrical connectors (probably brittle) on the BOTTOM SIDE of the fuse blocks. In my case, the bottom side of the under bonnet TCM B+ connection was the culprit. Of course, while I was at it, I clean all top and bottom connectors. Twelve years later, that cleaning continues to result in flawless operation.

 

Stratstone jaguar Huddersfield very kindly supplied the radio code this morning and that's now working, so one less issue.
Sat nav is dead though.

 

You've checked your fuses, but have you checked your relays?

 

In a word no. I am awaiting the arrival of a more detailed code reader to see what that shows. I've read p1000 is not a fault but shows the vehicle hasn't completed its checks fully and needs to be driven further. Possibly upto a thousand miles.
juggling this with the fuel pump swaps on the convertible aswell as the British weather!

 

1000 miles is rubbish.

You can read about drive cycles on here to get monitors to set.

Any that don't set quickly - investigate rather than keep driving.

 

You are having an electrical nightmare and you haven't checked a fundamental part of the electrical system. Your code reader won't tell you why the sat nav isn't working, but a multimeter or a test bulb will. Now I know you are going to say the sat nav isn't that important to you, but in my opinion its daft not to start fault finding with something so obvious and easy to test - it might be nothing, or it might be a problem with that entire section of the fusebox. It's just such an obvious place to start testing, before worrying about the mysterious black boxes and network cables.

 

battery needs to be 12.6v or above after sitting overnight with no charger or tender hooked up during that time.

nice one zray. I will check that thanks.
