#35 of 45 TOD will not engage but indicates an error in Red by popz1947 Mar 08, 2009 (6:39 am)
Hi When I push the Torque on Demand button on the dash of my 2000 Trouper instead of the display going to Auto and everything turning green, I get a red error where it usually would show Auto.    Does anyone have any thoughts as to what is no working correctly? and hopefully it won't cost a fortune to repair the problem.    Thanks for any of your help.    Popz

#37 of 45 Re: 2001 TOD auto flashes but does not engage [hiprollc] by rflemin Mar 10, 2009 (11:48 am)
Replying to: hiprollc (Sep 01, 2008 8:09 am) I've got a '98 Trooper with TOD. Several times lately, it has "paused" while on a bumpy alley -- it didn't completely die, but the POWER, etc. lights came on and it seemed to be driving at a lower gear, then back to normal. Once it died, but restarted once I shifted to Park. About an hour and a half ago, it did the 'pause', but kept running. Ten minutes later, it died, would not restart, and the TOD Check light came on and flashed. I put an OBD II tester on it, got a "Link" display, but nothing else. I coasted down to a parking spot and walked home to do a little research. I'm going back to see if I can find loose hoses or wires around the transfer case and to pull the battery cable. Anybody got any idea what could cause both the TOD Check light and Won't Start? And what I can do about it? Oh yeah -- about three months ago, the transmission died (no second gear) and I had a used one put in. This happened out on the boonies and the transmission mech said he couldn't get rebuilds, so to go with the used one. It's been a little cranky about shifting into Park ever since. Maybe something wasn't installed as tight as it should have been? Thanks for any advice. Replies to this message: rflemin (Nov 04, 2009 12:43 pm)
#38 of 45 TOD check light flashes codes 13, 14, and 24 by dirtroad565 Apr 21, 2009 (2:48 pm)
Tod check light on my 2002 Trooper flashes codes 13, 14, and 24.   Bought a shop manual on CD.   Shorted pin 8 on C-63 to ground and generated aforementioned trouble codes. Presumably, the code 13 (reference short circuited to ground) is causing the other 2 speed sensor codes.   Per shop manual, pin 15 on the TOD Control Unit is connected to pin F-11 on the Powertrain Control Module through connectors B-49, H-12 and H-57 respectively. Disconnected wiring harness from TOD control unit and read direct short to ground on pin 15 of plug B-49. Went to pin F11 of connector E-54 on the Powertrain Control Module and read no continuity to pin 15/B-49 or short to ground. I did have continuity between F11/E-54 to pin 16 on what I believe to be connector H-57. The connector between H-57 and B-49 is H-12.   DOES ANYONE KNOW WHERE H-12 IS LOCATED? I have practically torn the car apart looking for this connector. The parts location page in the manual is of little or no help. I am ready to rig a jumper/bypass wire from pin 15/B-49 to pin 16/H-57 and hope for the best. All suggestion are welcome.   p.s. I have just replaced the second transmission in two years. I am presuming that someone pinched a wire during the process causing the TOD short circuit issue.
#39 of 45 blinking lights on my dash board what is that by anyway Apr 21, 2009 (2:55 pm)
I have a 1996 isuzu trooper and for some reason my dashboard is making this clicking noise and the battery light brake light and other lights come on. Then when the clicking starts my sensors to show if i am over heating or if the battery voltage is low starts to go back and forth like crazy. Can someone please tell me what that is and how to fix it. I am just hoping that i am not on the freeway driving and my car stalls because of this problem.
#40 of 45 stuck by armytrooper Jul 25, 2009 (5:34 pm)
I think my car is stuck in 4 wheel drive. I got in the car today and the Torque on demand rear wheels are lit up green, I have no idea how this happened or how to fix it. Replies to this message: rflemin (Jul 26, 2009 6:49 am)

Replying to: armytrooper (Jul 25, 2009 5:34 pm) Whenever this happens to me, it's because I hit the AUTO button on the dash instead of the Hazard (4-way flashing lights) button that is right next to it.
#42 of 45 02 Trooper 4wd will not disengage by anjinsan5 Nov 04, 2009 (11:48 am)
I just bought a 2002 Trooper with 95K miles on it. The TOD display is blinking all four wheels and the CHECK light below the display. I read a bunch of the posts here and figured it was the VSV like others have talked about. The Blue swich was broken so we replaced both of them. The problem is still the same.   the Auto switch does nothing. If you have the 4wd shifter in 4 wheel high truck drives fine. Can't get it to shift into 4 wheel low but if you put the shiter into Neutral (I assunme this is correct) the truck is literally in neutral no matter what gear the column shifter is set for. I am about to lose my mind with this thing... Can any one help me with this? Could it be the TOD ESM? The speed sensor I read about? Also the ABS light is lit, could that have any significance?

Replying to: rflemin (Mar 10, 2009 11:48 am) Just to follow up: I replaced a relay and got the Trooper started, but it kept acting funny and finally died. I had it towed to a shop where they said that the battery had overflowed (don't think so, cause it was fairly new and I had just washed off some corrosion) and the fuse box was badly corroded. They cleaned and rewired the fuse box and replaced the battery and the Trooper has run fine ever since.
