Found fault code P1590 in my Rave info

it says

P1590 ---- ABS rough road signal malfunction ---- hardware is OK, but the SLABS ECU is sending an error signal.

P - 1*** codes are manufacturer specific codes which maybe associated with a particular ECM/ECU, component or module

hope that helps :D

guess it looks like a trip to land rover then. With abit luck it would end up costing a mint!

Or find a good independant specialist.

Generic fault readers are ok, but are limited in their capability. You really need someone with a proper LR specific Diagnostic kit.

Whereabouts are you?? (might be able to help ;) )

That's very interesting. It looks like I may have that fault on my 300 Series Discovery. When you start the vehicle the ABS light comes on. When you move off the ABS light goes out. However a little while later the ABS light comes on again. It started happening when I was off roading in the Pyranees. The brakes work fine BTW. The tracks were not hard but very bumpy. Does this sound similar ?
