All the TOD equipped models have SOTF.
 
Check the 4-low and see if it engages. If it doesn't then it's likely the SOTF vaccum or the unit itself. I left mine in AWD mode for a whole winter and when I tried to put it in 2wd, it wouldn't work. Same error message. Turned out because I hadn't changed mode (2wd -> AWD/4wd) the lube dried up and the unit siezed.

TOD Error by pooper1

My TOD is "working", that is, it does come out of AWD - but the dash lights never recognize it, and eventually the error light flashes. It had the engine completely rebuilt, and sat idle for about 3 months waiting for that, but it was in 2WD when it went into the shop. Any ideas?

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 .

Hi,
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.
any ideas?

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.
