Does anyone on the forum know how to turn off the Odyessy mode of a TMCC engine when they don't have the on-off Odyessy switch underneath?
A hobby shop owner told me there is a way to do it with the Cab1 keys?
Thanks!

If you have the early version of Odyssey without a manual switch then it also will not respond to the CAB-1 enable/disable commands. It won't hurt to try though; possibly the board was replaced with a later version at some point?

Disable Odyssey: AUX1 + BRAKE + 7 + BRAKE

Enable Odyssey: AUX1 + BRAKE + 9 + BRAKE

The loco should not be moving and no more than a second or two should elapse between each button push.

Thank you, I will try that.

The boards for early lionel engines with odyssey, but no switch, had two pins which when connected would turn odyssey off. I personally feel odyssey is an abomination and destroys the basis notion of prototypical running and have never bought and run an engine in odyssey on my layout! Around 2002 I bought the dreyfus engine which I thought had an odyssey switch. It didn't!! I complained to Marty Pierson who was manager of EE at Lionel and he told me to send the engine to him. He had one of his people put a switch on the 2 pins and reprogramed the board. Possibly some of the electronic experts on the forum can tell you how to do this !!

I don't run Odyssey, on my layout, so I was comparing the boards and noticed they were the same. I had planned on adding a switch to the 2 spots on the early board, but have not got a roundtuit yet. I would like to know what reprogramming the board means.

This is just a guess, but since the board has a microcontroller chip on it, I suspect that reprogramming involved updating the software on the older board, so that it would recognize the switch and perform the enable/disable functions. It would be interesting to know if the reprogrammed board also now responds to the CAB-1 commands to enable/disable Odyssey.

I can't check this out as I sold the dryfeus and 12 20th century limited cars when I bought an ocela.

I'm the one who bought Stan's Dreyfuss so I'll try to check this out this weekend.

I now seem to remember that Marty apologized and said the only way to turn odyssey on-off was through the switch! That was fine for me as I wanted it off and never brought the switch to the outside of the engine. It will be interesting to see what Matt finds!

Yup, best I can tell, the switch is the only thing that has any impact on odyssey.

Bob, I have one loco with the switch and one with out the switch. The only difference that I can see between the boards is one has the leads going to the switch the other, just has the spots, where the leads would be soldered to, if it had the switch.

Lisa Marie Tahtaras, check your email.

Hi Bob,

I received your photo. I will try to check out my boards, very closely, in the next few days.

Lisa Marie
what did you find when you checked out the two boards as per bob's email?
stan

any update on this?

If you can turn off the speed control on boards that dont have the switch by installing a switch, that would be great. I really dont like the speed control.

Can I ask, what is the reason for turning off Odyessy?

I think there's basically two reasons for disabling Odyssey:

1. When building a consist/lashup with more than one Odyssey equipped locomotive, Lionel recommends that only the first unit should have Odyssey enabled. Otherwise the units could fight each other, sometimes resulting in burned out motors or electronics.

2. Some folks just prefer running their trains in the traditional way, with no cruise control.
