dash lights

Got into my D2 v8 auto this morning and the sport mode light is on on the dash and won't go off at all, has anyone got any ideas?

Usually M+S lights together indicate a problem with the XYZ switch on the box. Do they both come on with the ignition self-test? What happens when you shift to Low box?

Yes they both come on but the M light goes out and the S stays on. They don't flash.

didnt you press accidentaly the mode switch? press it again to see what happens...if no joy move the transfer box lever in low and if the lamp will switch to M it means there's a short in the switch or it's circuit...we'll speak then

My S light was lit this morning, pressed sport and it went out, I assume I nudged it as I put it in gear.

Mine won't go out when I press mode.

did you select low on transfer box too?....unplug the switch see what happens

Yep I selected low and no joy

I just unplugged it from underneath the selector cover and the S light has gone out.

then the switch is blocked closed or a short within it, untill you fix it, as long as you dont want to select sport or manual you can leave it so otherwise you'll drive in S mode all the time

I must say I can barely tell the difference between sport and normal......

Makes a big difference in hilly country, as it doesn't change up quite so readily.

Could it be where it's plugged in underneath the cover that's the problem?

Just had another go with putting it into low and it now goes out when I do this but when I stwitch the ignition off and then back on the S is lit up again???

there;s some throuble with that switch's circuit cos it must go to M automatically when you switch to low if the mode is selected, as long as it stays off with switch unplugged the problem is above the plug... also if your hi.low switch doesnt work well(and that's very common) selecting hi or low will not affect it much cos there's no signal, and the hi/low switch has no warning, you can check if it works only with tester

Could it be the circuit where it plugs into underneath the selector?

IMO there must be something as long as unplugged it doesnt happen, see the attachment, get a multimeter and check if you have earth on the pin of the selector module corresponding to pin 7 of the plug(blue/orange wire) ... concentrate to not mix pins...if you have earth there that's the problem, it means it's a short to earth within that circuit and the ECU goers automatically to sport and the hi/low switch doesnt work to make it go to M in low...if there's no earth on that pin but you get the S light anyway then IMO start to source another transmission ECU

RAVE - DESCRIPTION AND OPERATION 44-5 said:

The cover incorporates lever position indicators and the mode switch. The lever position indicators illuminate to show
the position of the selector lever. Illumination is controlled by the Body Control Unit (BCU). The mode switch is a non-latching
hinged switch that, when pressed, connects an earth to the EAT ECU to request a change of mode.

Problem solved, I got a new gear selector and the sport light is now out.Thanks for all your advice.
