T200 Isuzu Trooper, Automatic, 137K, TOD check light. About a week ago I hit a bit of high water with a little more force than I thought; didn't look like that much water. Almost immediately after the TOD check light began flashing. I think maybe a sensor got too wet. Over the past week the flashing has subsided somewhat but still cycles intermittently. Anyone experieced this and what was your fix. Am hesitant to take it to the dealer since the TOD still works flawlessly. Have tested it several times since the flashing and everything seems to work properly. Think maybe just need to dry out? There are at least 3 different electrical connections in the area adjacent to the front differential. Not sure what to do at this point other than see if problem will go away. Comments welcome.

the most common failure is actually the sensors on the transfer case you actually replace the whole harness on the t-case it comes complete with both sensors if its currently working fine then thats most likely cause if it were much of anything else it wouldnt function properly
