Sounds like it could be the switch on the front axle not responding when the axle shifts out of engaged position. Try unplugging it and see if the indicator light goes off, although I am by no means an expert on the TOD system. I am going by the fact that all the front switch does is indicate the status of the axle and you say it is disengaging properly......HTH

Just took my 02 trooper to the only dealer left in my area . Had then run the diag on the TOD system. Want to replace the wheel speed sensor and replace the Vac solenoid valve . $1342.00 in Delaware . I will pass on spending that since I have a 07 Mitishi Outlander 4 wd ., not a Trooper but great crossover .
#61 of 98 CHECK LIGHT ON TOD
Jun 27, 2008 (10:42 pm)
I have a 2001 trooper and lately I have had the red CHECK light flashing on the TOD panel without using the 4wd. it starts flashing about a minute after the car is running again without the 4wd selected.

I had the same problem on my 1999 Trooper. I had the Flashing Check light on the TOD panel AND the Check Engine light was on steady...Want to know what the fix was??? No $1000 speed sensor job...the wiring that runs along the drive shaft was corroded and exposed....I had some new wiring put in and TADA! no more flashing TOD check light and no Check Engine light!

My light is the green light that flashes when the TOD is activated. I'll check the wiring and let you know. The check engine light is not on. Thanks Butch

Pretty much same problem here on my 1999 Trooper. Had transmission rebuilt by local rebuilder. When I drove it out of the shop, I noticed (for the first time in 9 yrs) the check light went on and the two rear tire icons were blinking after a few blocks. This was in 2WD. I clicked it into 4WD and all four tires lit up, but the blinking stopped amd - AFAIK - the check light did not turn on. Didn't stay in 4WD too long, reverted back to 2WD and the check light and blinking rear tires came on.
Given that this has never happened before the transmission rebuild and then it happens immediately after I picked the car up from the rebuilder, I want to believe they must have mucked up some sensors, tubes, or wires. I am no mechanic and my knowledge of cars is limited to knowing that they somehow internally combust expensive fuel.
The transmission rebuilder has no idea what's happening and asked me to bring the car in on Tuesday 9/9/08
Comments? Suggestions? What should I tell the transmission guy? Oh, yes, am I likely to hurt the trooper by driving it while that check light is flashing?

My problem ended up being 2 vacum sensors for the 4 wheel drive. They are on the front axle. I've had a slip a couple of times lately with the transmission. Is there any way to check the fluid on these sealed ubits? Thanks Butch and good luck on your problem.
#66 of 98 1998 trooper 4wd problems
Sep 09, 2008 (3:07 pm)
my tod cluster flashes the red check ligt and the rear wheels constantly flash.the four wheel high/awd doenst work.the solenoids read the correct ohms and have voltage.ive taken the actuator apart also and changed the front diff.fluid.where do i go from here?the 4 wheel low has always worked until last month and now wont work either.i went to change the transfer case fuil and it only had about a 1/2 quart in it.didnt see any metal in it.would this mean the transfer case itself?i thought when shifting into low range the trans.case was the only thing that locked the front?or can it be something else.any help would be great as i just bougt this used a couple of months ago just to have a 4wd vehicle and winter is coming.thanks for the help.

#68 of 98 FIXED! 2001 would not go into 4x4... here's how...

Check the above link for into how to locate the VSV on your front axle. (Vacuum Switch Valves.) I fixed mine FREE as follows:
First, remove both VSVs from the axle. They are both mounted on a little rectangular plate, and both will come off by undoing two 10mm nuts. One VSV is BLUE, the other is GREY. Label and unplug all the vacuum hoses (carefully!) and then disconnect the electrical lead from each VSV. The electrical connector plug is a bit tricky to disconnect...you have to pry up a thin, springy brass colored retaining wire on each side of the connector, then GENTLY pry the connector off with a twisting motion of a straight-blade screwdriver. EASY DOES IT because that thing is fragile..if you crack the connector, you're 99 per cent hooped.
Once you have the VSVs off, use little jumper wires with alligator clips on them to connect to the electrical spades inside the plastic housing of the VSV. Hook the other end to the car battery and listen for a VERY QUIET "click" from the solenoid inside the VSV. This solenoid controls the vacuum flow to the vacuum actuator, which moves a toothed sleeve back and forth across splines on the ends of the axles, which is what drives the front axles when you press the dash SOFT switch.
The whole purpose here is to get the VSVs clean and operating properly. You might not have to replace them at all...just shoot some NON-GREASY electrical contact cleaner into all the outlets of the VSV and operate the solenoid a whole bunch of times...get it working freely again. (NOTE: DO NOT USE WD 40 or anything greasy / oily to spray inside the solenoid!!!!!!!! Make SURE you use a solvent based cleaner that DISAPPEARS completely when it evaporates. Spray some into your hand to make sure. Use electrical contact cleaner, specifically made to clean electrical parts. TRUST ME HERE...test your product on your hand to make sure it does not leave ANY residue.)
GOOD LUCK DOODS!!!!
