western Posted October 9, 2007 Share Posted October 9, 2007 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 Quote Link to comment Share on other sites More sharing options...

Porny Posted October 9, 2007 Share Posted October 9, 2007 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??

Ivan Posted October 10, 2007 Share Posted October 10, 2007 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 ? TIA Ivan Quote Link to comment Share on other sites More sharing options...
BogMonster Posted October 10, 2007 Share Posted October 10, 2007 Ivan, Yours is probably a simple matter of a bad wheel speed sensor. Not an uncommon fault on early ABS systems but you still need a computer to find out which wheel. Quote Link to comment Share on other sites More sharing options...
