How to Check the Engine Temperature
I have an 06 model with the both the select and reset switches on the handlebar rather than the reset on the console, but would think the procedure is the same.
- Turn bike off
- While holding the Reset switch (the righthand switch on '06 bikes), turn the bike on, and continue to hold the switch for approximately 5 seconds until "diag" appears on the clock display.
- Keep holding the Reset switch and hold the Select switch together for approximately 5 seconds until numbers appear.
- Scroll left or right until the function number 11 comes up, which will display the temperature. Mine is in farenheight.
