I live in WV where there aren't any mechanics who work on Isuzus. On my last trip to MD, my rear brakes, calipers and rotors went out. I had them replaced and am now back in WV. Now I am having problems with the TOD indicator light (the rear wheels light has gone out). At times when I am driving the light will come on. I have read many posts about the TOD system but wonder if there is an easy way to figure out whether this could be a dirt problem on the sensors? I was told by one mechanic who claimed to know a little about Isuzus that if I didn't have cruise control, the sensors would need replaced?? My next trip to MD isn't scheduled until next month and I don't know if I should be driving under these conditions. I'm sure you can tell, I am not a do it yourself kind of person. Any help would be greatly appreciated. Thanks, De.
