Transmission, TOD and hub questions.

My VX manual shows DTC P0705 Transmission Range Switch
(Mode Switch) Illegal Position . . . . . . . . . . . . 7A1 30

First thing I'd check is the 15A fuse (CB 15) in the engine compartment. According to the manual "This fuse can burn due to a short circuit in the backup lamp." Does your back up light come on?

Also, Tom's toad mode has the rear drive shaft disconnected which is why his odometer doesn't advance while being towed.

So you have less miles on the odometer than you have driven? Strange that the odometer does not count miles when the TOD is off.

Also, Tom's toad mode has the rear drive shaft disconnected which is why his odometer doesn't advance while being towed.

Yah, 'toad mode' = being towed (4 down).

I only pointed out the 0 miles accumulation on the ODO (when being towed) to stress the point that you should do both the TOD disconnect and the locking hubs for best results. It's all well and good to cut power going to the front but if the front end is still spinning, then you really aren't reaping the full benefits.

Thanks I checked the fuse and it looked fine but I replaced the fuse anyway. I cleared the codes last night, so if the code reoccurs I can then look at replacing a part.
FYI: the CB 15 fuse is in the side panel of the dash, the engine compartment fuses are EB #s so if you are looking for a fuse the CB fuses are in the dash and the EB fuses are in the engine bay.

Well on the way to work the indicator light started to flash between neutral and drive and the shifting started to slam from first to second and second to first on down shift, so I shut it off and when I restarted it is was normal again. I am want to order the part but code P0705 says it is the "Transaxle Range Switch Circuit" but when I go to the Isuzu parts page I do a search for Transaxle Range Switch Circuit and there is no such part shown under that name, but after doing a few searches I found it is also called the "Neutral safety switch" does this sound right to you guys? I was looking here http://www.stcharlesautoparts.com/ I did find the neutral safety switch but no picture showing location, is it in the same place as the Trooper?

Should I replace the switch or could it be something else causing the issues?

I did have to replace this same part in my 96 Trooper not long after I put in the remote starter in it too.
