I -always- put it in RABBIT SPEED -before- going into SERVICE MODE. No settings can be changed once you are in SERVICE.
The -first- display when SERVICE MODE activates is the indicator for SPEED which -always- displays "1" LOW whether the engine is running or off.
If there is -no hydraulic sensors/pressures to affect the indicator, shouldn't it display "2" HIGH ?

Enter service code 10. The character display will show the operating conditions for the automatic travel speed change:

101 - This number indicates the LOW speed mode.

102 - This number indicates the HIGH speed mode

-This- is what I have been referring to from the first post.
This is the indicator that shows "1" LOW.
This is what I have asked about.
This is the code.
This is the FIRST code that shows after going into SERVICE MODE.
The "1" is the FIRST number of the code.
The "0" is the SECOND number
The "1" INDICATES LOW.
Apparently you don't understand what I have been writing.

Does anyone know -IF- the DISPLAY should read "2" HIGH when accessing SERVICE MODE and the engine -not running- ?
If -YES-, what suggestions do you have for -causes- ?

From my FIRST entry
Checking things in SERVICE MODE it -will- travel fast when I set 16-13 (travel pressure switch). There are no error codes.
However, the STATUS OF TRAVEL SPEED SWITCH (10) always shows - "1" LOW - even when the CONSOLE shows RABBIT. (engine running or not)
The travel has been working and switching back/forth, but just quit.

Thank you anyway for your responses.
