The TOD was flashing in red letters underneath TOD display of four wheels picture "CHECK". The manual says to stop vehicle and turn off engine and restart to check if message displays or does not display and for further information contact ISUZU dealer. I called Isuzu local dealer and left messages with two guys who work with Troopers and it's been a week with no response. I spoke with a transmission shop and they had no clue but were to get back to me about anything they could find, been a week also no response back yet. Anyone know what indicator this is for the vehicle? It's only flashed on one driving occasion. It would flash once to twice when kinda of starting to roll after a light, and flash rapidly when coming to a stop. But just once in awhile engaged in regular driving. I stop the vehicle when this happened and it's not flash again since. Any clues, any body? <img src="/forums/images/graemlins/patriot.gif" alt="" />

Is your 4WD engaging and disengaging properly? If not, the most common problem is a sticky SOTF actuator. This is what actually connects the front axle to the driveshaft when you shift into 4WD.
