Guys
I had to get the jag on the road today as a last resort normal comes out in the summer i has previously removed and charged the battery after it being the garage for 3 months, started no problem.however after 1/2 an hr on the motorway i lost my cruise control a little time later i had an abs warning light come on.I parked up at work and when I started it up to return home i now have a gear box light as well,it drives fine no issues and advice ???

 

The symptoms are all of those for a bad battery. Have the battery load tested. You also need to get the codes read. It will help with a diagnosis.

 

Cheers will get it sorted tomorrow and let you know

 

You will need to update your signature to indicate the model and year of your car. A general location would help, too. Help us help you.

Another likely suspect is the (double) brake/cruise control switch. I believe it shows as a transmission fault on the earlier car...

 

You leave the car garaged for months on end but NOT on a battery tender? There lies the likely explanation for the selection of weird electrical faults.

I've added vehicle details to your forum signature and this will appear with your next post. I'll leave you to update your Location.

I'm a little impressed it started at all.

 

Guys
i made to work and back today same issue with the addition off the air bag light now on as well got it home removed the battery have a new one coming tomorrow.
As for codes etc auto electrics is not my bag more mechanical is this an easy fix ?

 

You'll be unlucky if the new battery and a code clear doesn't fix things.

Graham

 

Yes, if it's the battery - as sounds likely.

Charge any new one if you can as despite what sellers tend to say they usually do need it.

If it doesn't fix it come back to us. (Or if it does!)

 

Guys please see the lights i have on my dash,changed the battery still have same issue

 

any help would be appreciated

 

The MIL is lit (the one on the left) because relevant DTC's (Diagnostic Trouble Codes) have been set. Some codes clear once the cause is fixed; others require to be cleared with a code reader or scan tool.

ABS and DSC System Fault separately or together are regulars. You will find many threads on the topic.

^^ Agreed. If you have installed a new battery, use an appropriate OBDII code reader to clear your codes (after writing them down for future reference). Then, drive the car and see if they return....

 

So, been getting intermittent warning light (centre dash display only, not ABS symbol). Checked codes and none present. Washed all 4 speed sensors about a month ago. Warning stopped, until yesterday when the same central display reappeared. Checked codes again and nothing. Checked battery and all readings showed a good voltage with both engine off and on. Drove today and no light.

My concern is it's MOT is due soon, which it will fail if the warning light decides to reappear whilst being tested.

Anything else I could do to check/test whilst I still have time?

Thanks
Jules

 

A generic code reader will not display brake codes. You need to visit a shop with jag software to identify the problem.
