There is a ton of stuff for TOD diagnosis in the manual. It's mostly complex electrical things that they use the Tech 2 Scan Tool to figure out. It says the TOD control unit rarely fails and bad connections are most likely the problem. It does mention the rear wheel spin you have. If the TOD check light is not burned out, but is not blinking, there still could be a code stored. You connect pins 4 and 8 with a wire at the data link and then turn the ignition on to read the codes by the blinking TOD check light.
