Reprogramming Code for Lionchief 2.0 + GG1? 2034020

I don’t have a Legacy base. Cab1 and command base. No single bell after holding aux1 in step 6.

I've never had to do step #6 to successfully set the ID for LC+ 2.0 locomotives.

Headlights are flickering, engine stops responding to remote, after I reprogrammed using #5, #6 & #8. Original problem was engine didn’t recognize TMCC. Wanted to start in conventional. Actually did a jackrabbit start, too. Thanks.

Why aren't you following all the steps?

John - don’t know where you got the idea that I’m not following all the steps. As directed in the manual’s reset instructions, I do not get a single bell ding after step #6 using either AUX1 or 0, or both pressed simultaneously.

In addition, please note, it further states “Restore power to track and operate locomotive as usual.” Yet nowhere, in the 7 steps, does it indicate when to d/c track power, which is a preliminary necessity to “restore power to track”

I’m also wondering if the reprogramming code has been omitted by accident, or, if it’s no longer needed to reset newer engines?

Thanks for your reply

Mark, I got that idea from your post.

They usually state it, but you turn off power before you start the checklist.

I'm guessing step #6 is a mistake, my LC+ 2.0 engines don't make any sound no matter how long I hold AUX1/0

OK GRJ, I see now how what I first posted could cause confusion. Those were not the steps to reprogram. Those were the reprogramming codes that did not work when I tried them. But in my defense, there is no step #8 in the manual instructions.

I apologize for not being clearer, and I had to ask someone else to look at this post, because I certainly didn’t understand what you were saying. So, in the initial post, the numbers referred to are reprogramming codes, not the steps in the manual to reprogram the engine. Sorry for this.

From an unnamed Lionel Service manager:

”There is no code need for programming or addressing an engine. It is whatever number they desire. Put the switch in prg, take cab2 press eng then a number and press set on the remote and you should get a horn sound. Then put the switch back to run”

In a nutshell, the procedure for reprogramming a TMCC engine has changed, and unlike previously, a reprogramming code is no longer needed. Maybe this is old news, but was an unknown, confounding variable for me.
