The transmission is electronic and the mode switch is mounted on the trans where the shifter enters the trans. There are electrical contacts in it that are known to corrode or require adjustment. commonly there is a problem with shifting and the trans telltale lights not being correct with shifter position. There is a very specific way to set the mode switch up properly, I think if you do a forum search you can find it. IF not, post again and maybe someone can help. good luck

It would help to know what year and model, but in general, I don't think the ecm has anything to do with the mirrors. Sound like it could be a connector somewhere being loose or a bad switch for the mirror. If you have the 4L30E trans, the mode switch on the trans may need attention. They get corroded due to position and can cause shifter problems. Do a forum search to see what the general write ups are before tearing in to it. Good luck.

I really hope someone can help me. I ran into a situation today with my 1990 Isuzu Trooper 5 speed manual. With a 2.8 liter V6.
  
Today I stopped to wash my car at the car wash. After I did so, I jumped on the hiway. About a miles down the freeway, My vehicle stalled. On the side of the freeway, I went thru the process of problem solving the situation. This is what I had done....
  
First and foremost, I checked the distributor and router for moisture. In doing so, I found no moisture. I then checked all the plug wires, and everything was secure and dry. After that, I went ahead and checked to see if I had blown a fuse. In doing so, nothing was blown. I also checked the fabric wire fuses and rearanged the relays next to the fuses. Then I started to think that there was fule pump problem. I went ahead and put some fuel in the carb from a gas can I always keep for safety purposes. I added not too much and not to little. In craking it over, nothing fired. It just turned over. So then I got thinking, maybe my coil was shot. I went ahead and purchased a new one at the auto store and replaced the old one. To all avail, It still woudn't fire up. All it's doing is turning over. In the end, I ended up having to have it towed home.
  
So here I am, and I just don't know what to make of it all. When I look back to what I did at the car wash. I didn't open the hood this time to wash down the engine, so I don't know how water could have got anywhere. One thing I did do was spray under the engine and the under carrage. I always do so here in Colorado. Esspecially when the snow and mud collects underneeth.
  
If there is anyone out there that can help me troublshoot this problem, It would be soooo greatly appreciated....
  
Thanks a bunch....

I agree that it is weird that the engine would quit going down the road, but I think your ignition module probably died and that could be the problem. Either that, or your alternator quit and killed the electrics. You can have the alt checked. You seem to have covered the fuses and fusible links.....I don't have your engine, but the module is in the distributor. Last time I needed one it was about $40 bucks for an aftermarket model. Some parts stores have a tester for the module but I have found that it is easier to replace the module than trust the tester, since module problems can be intermittent. It is easy to replace, and I would carefully inspect the connectors on it too to make sure the wires are all intact. Make sure to use the packet of heat sink material that should be included with the module. Apply it to the base of the module where it seats on the distributor plate. Hope this helps. One guys opinion.

oil leaking from somewhere by jbdy

Hi My son just bought an 2000 Izuzu trooper it runs great, though it needs some parts replaced Timing belt. It has 130miles. It had it's transmission replaced however it is going through a quart of oil every 100 miles My husband thought it was a loose dip stick cause he could not see any evidence of oil dripping from any where, thought it might be the valve gaskets, no sign of engine trouble ,( rough idle , ect it runs real smooth) .
My husband is hoping it does not need an new engine!
any notable history about a problem like this?

The 3.5 engine does have a history of high oil consumption. Generally, it is considered a very reliable motor but the oil consumption you mention does seem to be excessive.
I think that running a product like Seafoam or Rislone or similar and a couple of frequent oil changes with filters right away may help improve things. That is also a common treatment for this motor. It appears that the oil rings on the pistons get gummed up and stick resulting in less efficient oil wiping and thus increase the oil consumption.
I am sure you will hear other items to check, among them the PCV valve and vacuum hoses, etc. All are good ideas.
Also worth mentioning is that when you change the timing belt , also replace the water pump and pulleys. This is because it is a lot of work to change the belt,and having to go back in to fix the pump or pulley bearings later is just not worth the risk. The factory usually recommends changing the belt at 100,000 miles.
 
Welcome to the Forum! Hope this helps. Try a search to learn more too!
Remember that, like you, people come to a forum because they are having a problem, so the questions and problems you read about are heavily weighted with negative impressions. Seems like people who own Isuzus and keep them feel they are worth it!!!

ATFDmike is a great source of info. My dad has mine now, but I remember burning about 1q per 1k miles on dino oil, with synthetic I stretched it to about 1q/2k miles.

A couple of other things of note about that generation Trooper. Spark plugs are recommended after 100K miles (most of change them before that). The rubber tube under the coil paks that extend down and cover the top of the plugs will likely be stuck on at least one. Use compressed air down the center hole in those rubber tubes to pop them loose...do not tear them trying pull them out since you have to purchase the complete coil pak with tube for around $150. Also, use only the plugs specified in the manual. I'll post below what my 2000 Trooper manual has. I had the RC10PYP4 Champions in my Trooper and put the same back in.
 
Manual:
K16PR-P11
PK16PR11
RC10PYP4
 
If you use another non specified plug (platinum or otherwise) you are almost guarantee to have problems and throw a CEL.
