Discovery 2 random warnings!

[just_william]

Morning all
My discovery 2 can occasionally bring on some warning lights on the dash, whilst driving along normally. They are:
Traction control
ABS
Hill descent.
Seems to only happen on shortish journeys (Approx 5 miles), They always come on together. Usually clear it by pulling in and restarting. A little annoying, just wondered if there is that magic sensor somewhere that might be causing this? Vehicle seems fine before, during and after.
thanks for any thoughts

Range Rover throws up all sorts of nonsense when battery is not in good condition.

Might be worth investigating if this could be an issue?

One of the things in common with TC, ABS and HDC is that thy all rely on information from the abs sensors on each hub. It could possibly be a dodgy abs sensor, but only by plugging it in to investigate any stored fault codes will you know for sure.

It could also be something horribly expensive...

Commonly referred to as 'The Three Amigos' & a search on the internet will bring up a wealth of stuff.

This is one example: http://www.lro.com/forum3/viewtopic.php?f=19&t...

Connection to diagnostics is the best starting point.

We all get those lazy, feckless, farting Mexicans at some point. The intermittent ones are usually shuttle valve but even that is only a temporary fix. Mine lasted 6 months and back they came.

The fix showed by Martin Hollings on Paintmans link is supposed to be permanent. It's being done to mine in March so we'll see.

Cheers chaps, gives me a starting point. Dont like that expensive word in there though. Will have to get it booked in sometime. Transmission and axles oils this month though!!

I had a similar problem, rough road traction abs light would come on. Finally traced to a worn wheelbearing(front).

[anonymous-user]

Yep, another vote for wheel bearings. Upsets the fine tune positioning of hub and sensor.
'Bout £250 a corner apparently as it's all sealed.

Had this on mine a few times,turned out to be a nearly flat battery,low voltage can set these warnings off.
