200tdimorgan Posted April 3, 2015 Share Posted April 3, 2015 Afternoon I've been trying to sort out an issue with the gearbox on my 04 auto disco. The m and s lights constantly flash, with the gearbox constantly in limp mode. Instantly thought the xyz switch was at fault, fitted a tested used one, no different, tested a second known working switch, no different. Plugged into various diagnostics (Snap on, hawkeye, black box) and none of them have any communication from the switch. I tried a used but working when removed EAT and plugged diagnostics back in, still no communication with the switch. Hoped this just meant a broken wire in the loom, however after a thorough test of all wires from switch to EAT, none of them were broken. All I can say from this test is that the only wire that came back live from the switch to the plugs under the centre console was the inhibitor wire when the selector was in P or N Does anyone know which of the other wires should be live when each gear is selected I have read through RAVE but it only talks about the W, X, Y and Z contacts, not which gear selection Trying everything before taking to Landrover to plug in T4 to see if that will shed any more light on the problem cheers Quote Link to comment Share on other sites More sharing options...
