Okay 1997 Disco with 83K miles. I was told it was one owner. It was serviced by a LR dealer and had a fair amount of work done to it including it's ECU (I was told there was a service bulletin about it?) And it had it's speed transducer replaced...what the hell is that? The truck is clean with only a few cosmetic problems. I did notice duct tape acting as a seal I suppose on the plenum leading away from the air box (where it clamps) I can't figure that one out. My questions are: The Check Engine light is on. In my experience (mostly OBD1 cars) that is only emission based. So thinking it might be O2 sensor etc. What else should I look at that may cause it? Now, I've had mixed problems getting the CDL into 4-lo and then back into 4-hi. All vehicles I have looked at have been missing the manual so I've gone by ear (are the manuals bonded with gold or what's the deal? :D ). A beeping noise occurs when I shift the t-case to neutral. Is this normal? Also, I couldn't get it back into 4-hi unless I let my foot off the brake. Correct? My trooper is shift on the fly so I'm not use to the disco's set-up. Also, silly question, but this has the CD changer under the seat. What function on the head unit controls that? And, if I'm driving and pull back on the steering wheel mounted control ACCEL RES for the cruise control, does that turn the system on? I haven't gotten CC to work on any of the trucks I've driven. TIA, based on what you folks tell me, and what goes on with the deal I may have a new-to-me disco tonight  Cheers, Brent | ||

Let's see here....what can I be helpful about.... First, the check engine light. See the tech section for a fix on that one. Otherwise I suppose it could be the emissions. Next, regardling the T-case. There is a beep when T-case is in neutral. Here's the thing, the T-case will "only" (not really, but good practice) shift from 4H to 4L and back if truck is rolling in neutral (gear selector) at no more than about 5mph. So the routine is: slow to speed, pop into neutral, and then right before truck stops moving, shift into 4L. It's not as smooth-shifting as you'd think it'd be and you'll probably hear/feel a clunk. I don't have the changer but if memory serves the "SEL" button controls head unit function. Cruise control. With truck over 40(???) mph, and cruise control button depressed (to the lower left of the climate controls, pull "SEL +" button till cruise takes over by pulling gas pedal away from you. To adjust speed upward, pull and hold that button. To coast, pull up and hold "RES -" button. To reset when cruise is off, pull "RES -" button and release when cruise takes over. Hope this all helped. | ||

Well, I did find a couple messages relating to the transducer - it's in the last answer here: http://www.motorcarsltd.com/ubb/Forum3/HTML/000088.html The apparently entire list of recalls and technical service bulletins for 97 Discos can be found here: http://www.alldata.com/TSB/68/97680606.html (Edmunds.com may have more detail.) The TSB related to the ECU is this one: TEC8616973 NOV 97 ECU/ECM - Intermittent No Crank/No Start >The Check Engine light is on. In my experience (mostly OBD1 cars) that is only emission based. So thinking it might be O2 sensor etc. What else should I look at that may cause it? < Someone else who knows this stuff better will hopefully answer you on that. I'd still be leery of that - at the very least, examine a recent smog report if they do those in your area. Doesn't the Disco have 4 O2 sensors? (And aren't they not cheap?) You've probably already seen it but the 4WD setup does have a diagram, either right next to it, around the dash above it or on the driver's visor, I forget where exactly. Sounds like you already got a better answer to your question about the 4wd though. | ||

Okay, we've called the dealer and made a deal... So it looks like I will be signing the paper work in four hours or so.... that is unless anyone can talk me out of it Just to be certain, the CE light is only emission problems correct??? [edit]I mentioned the duct tape on the intake plenum aft of the air box. It was not properly snapped into place. I'm betting it had an air leak. This could very well have caused the CE light to come on. If I end up getting the truck I'll run over to autozone and have the codes pulled.[/edit] | ||

FYI not sure what state you are in.. but a dealer has to sell the vehicle that passes emissions.. the days of "as is" in most states is illegal. The check engine light is most likely emissions based but you should be able to get the dealer to fix this. As for the hard shifting into and out of low gear.. this is typical of rigs that have not used the low gear in a while.. the linkage gets stiff... you will need to lubricate it with some penetrating oil. (look up in archives) | ||

Is it the red "Service Engine" light, or is it the amber "Check Engine" light? If it is the "check engine", have them read the code and tell you what it says. That's the "nice" thing about having OBD-II, the truck is trying to tell you what its problem is. It may very well just be emissions. But, it could be more. Have them agree to fix whatever's causing the light, regardless of what it is. Or, better, have them fix it first, before signing. Look at : http://www.robisonservice.com/servicedep/rover_obd2.asp As you can see, emissions may cause most of them, but some of them could be something else. Find out what's wrong with it first. Did it have a valve-job in its recent past? -L | ||

Like Leslie said it could really be anything with the CE light. 96 on up are OBDII and have many more codes that throw than the old OBDI systems (not just emissions). Have them read it and tell you what it says. As far as the CD changer, when you push "Band" on the head unit it will change between FM1, FM2, AM, CD, in that order. It took me a while to figure that out too (accident actually). And I think you were asking where the master CC switch was. The Brits thought they would use neat little icons that nobody would understand - that's why you can't find it. It's next to the fog light switch under the clock. The icon is SUPPOSED to be a freeway with an overpass when it actually looks more like an airplane. About the CDL - when you get it functioning right make sure to engage it once a week or so. That will keep the gears and engaging mechanism working right. They have a history of freezing up when not used often. Hope that helps and happy Rovering! | ||

Hey, good luck, from someone who recently did the paperwork thing too. Soon everything outside will seem very small and quiet. Except, of course, gas prices. |
