Check Rear Lights - Cruise Control Inactive
#1
![Default](/forum/images/icons/icon1.gif)
That may not be quite the wording but I keep getting this warning on the dash of my car. All the rear lights are fine (except the high level brake light which hasn't worked for a long time, if at all whilst I have had the car). It comes on pretty much every journey but I haven't managed to figure anything specific which triggers it.
Any suggestions?

andyps - Read through the links below. Hopefully one may help to answer your question. I am working on the first one with my own car, since I am getting an error message and the bulb is fine - and I can see the melted wire.

I had this problem a while ago (cruise unavailable/check rear lights) and I figured it was the brake switch but as suddenly as it appeared it went away. Well it has come back again now for several days and I am planning on bringing the car in to address a bunch of small things, one of which will be to get the switch replaced.

I also have had the 'check rear lights/cruise not available' but apparently found the issue associated with the console 'cruise' switch. It would never occur with the CC off, only with it on. Short of removing the switch and treating with some contact cleaner I 'exercised' it a hundred times and the problem seemed to have gone away.
While the brake switch is the most likely culprit there are other things, such as the rear light grounds and the CC switch that can invoke the message.

2006 xkr, 38,00 mi. Like may others I had a check rear lights in the window and the adaptive cruise did not work. I did have a bad console switch, changed that and that didn't help the cruise. Did all the things that have been suggested in this forum. Suggest you do all the easy things first, clean
the bulb contacts, check all the wires and the grounds. If that doesn't work then most likely it is the brake switch. I changed the switch and that fixed it all. See my earlier post on that. Good luck!

My Jag specialist has told me it's the security & locking control module that needs replacing so I've been looking for a used replacement, any comments anyone please?

oKay here goes
Complaint: on startup, all is well. Then after a few km of driving, the amber warning dash light comes on with " Cruise not available" and " check rear lights" warning text messages.
Correction: " Checked for stored codes . Found P1571. Brake switch fail, order new switch, Removed and replaced faulty switch, clear codes and road test ok"

$198 CDN plus two hours Jaguar dealer labour charges plus taxes.
Hope this helps

I've now checked the error codes & none are shown & as the reader confirms the VIN I think it's probably communicating correctly.

Gus, I get no response at all from the cruise control.

I haven't checked codes yet and will leave that for the shop when I bring the car in. I am 99% certain though that it is the brake switch as the amber light and messages (cruise not available/check rear lights) will come on after a few minutes of driving. The weird thing is that until the warning comes on I am sometimes able to engage the cruise for a few seconds but eventually the "cruise cancelled" notice comes on and I eventually get the amber/messages.
When this happened last year the problem actually totally went away on its own after a couple of weeks but now has obviously come back and doesn't look like it will leave on its own.

If it was the brake pedal position switch that was at fault wouldn't that be throwing a code P1571 as reported by Boomersaurus?

Gus, please excuse my ignorance but power what off, there's no response from any of the adaptive cruise control buttons & the handbook makes no mention of an on/off switch?

There are two microswitches inside the brake pedal switch, and if just the cc set failed it might not throw a code, but I don't know that for certain.

Needless to say, that switch has no effect at all either.
