DTCs readout does not work.

Thanks for your response Mike,
I did try to get the TDCs, but I couldn't. It would always display the sensor values. I followed his directions both for the sensor readouts and the TDCs, but it always displayed the sensor values.
I gues it's the last step: "Wait 20 seconds, then simultaneously press [REST] and [O] buttons for more than 3 seconds." Trying to hit the two buttons simultaneous, I guess one gets pressed first. If I press the rest button first I get the sensor values, and the [0] the system turns off.
