Hey Forkliftt. Was curious if you got it sorted out.

Jplayer, go read my long post above. You're not realizing what he means. The code isn't on the SepEx box, it's on the MIB (main interface board). The code is a 60. The function is 3 (really 03) which gives you a display on the MIB of "0360". If everything was working correctly, the MIB would read "0300".

Curtis flash codes are two digit. So 3 blinks followed by 6 blinks isn't "thirty six" it's 3, 6. 3 would be the group of errors and 6 is the specific error for that group. Sometimes it helps if you know what the engineers who designed the stuff were thinking as far as how they grouped and designated things. I think these trucks use a 1244 but I could be mistaken. Remember, in these trucks, the SepEx is only for the traction motor and is secondary to the MIB.

Good luck all!
Justin
