TOD Help

You could crawl under the passnger seat (just remove it) and check for output at the TOD module.

Look for a light-blue wire at pin 4 (check my gallery for details).
When the truck is idling, there should be (low) voltage present here. This is a 50 Hz PWM signal. The duty cycle increases as the need for torque increases. There are a number of different paths to ground used by the TOD module, so I don't believe that your problem is here.

If any of your vehicle speed sensors went, a CHECK light would have come on your TOD display.

maybe try putting all 4 tires up off the ground with jack stands and try accelerating (carefully). Or find a beach and play in the sand a bit.

Ok, will check waveform, but is there a TOD master module somewhere? My guess is I fried the module, or if I am lucky only a part of it.

Look in my gallery. The TOD control module is located under the passenger seat.
