When I get the system into the "Collect Sensor Data mode", I get:
1- 88F
2- 84F
3- 87F
5- 89F
6- 196
7- 8'4
8- 98F
9- 33F
10- 125

Unfortunately I do not know how to get it into "Trouble Code" mode. I am also not sure what "9" is above and what unit "7" is in (when it is displayed there is a small circle on the top between 8 and 4. It changes with the engine RPM from about 7'8 to 11'0 (at 4000rpm)).

Any ideas?
