For the first time today, I decided to check the level of the fluid in my 3060 trans using the shift pad instaed of the dipstick, or so I thought.
Per the instructions, with the coach nearly level, warmed up (driven at least 20 miles) and engine at idle, I pressed the "up" and "down" arrows simulataneously. The display immediately went to the diagnostic readout (d-1 through d-5).
Any idea what I did or did not do to cause this? And how do I access the level sensor?
BTW, no codes came up.
Thanks
Andy
