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.

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!!!!

#70 of 98 2002 TOD display flashes CHECK light
Mar 09, 2009 (10:59 am)
Just recently on my 2002 Trooper the TOD display flashes the red CHECK light. In my problem, as soon as the engine starts the light starts flashing. Just the red CHECK light.
My "Auto 4WD" does not seem to work. The 4WD low does work properly.
I checked the vacuum solenoids and they seem to be functioning properly when I test them off the vehicle.
Any ideas on where to go from here?

I recently had the intake manifold values replaced on my 1999 Trooper 3.2 and now I have a problem with my display of the TOD the rear wheel display green flashes and the check light flashes red. My 4 wd drive will engage and 4L has no problems. Sometimes the transmission will slip. Help any answers?

It is a 1999 trooper with TOD System with 132,400 miles and i have had all the pcv, sparks plugs, intake casket value,value cover set. fuel links & in 2007 timing belt redone and head casket on the left side. Now the right side head casket redone and i smell no oil burning. In the display i have the front wheels and rear wheels in the display and the rear wheels keep flashing green on and off and they the light that reads check comes in red in the display area and flashes on and off. No problems putting the vehicle in 4 wheel drive. It is the 3.5 liter engine I got when had around 78,560 miles and I am the 2nd owner of the vehicle and has all the goodies like the moonroof and captain seats and etc.
