Master list of Decoder Resets by Manufacturer

Before you start read these:

1. Remember that you can only READ CVs in Program Track Mode / Service Mode

2. When trying to read a decoder and you get a manufacturer ID of 255 and / or multiple readings of 255 from the decoder for other CVs too, that is an error message.

3. When trying to read CVs of a SOUND decoder on an older Power Pro / Ph-Pro system box you might need a programming track booster like the Soundtraxx PTB-100.

4. The manufacturer ID is for the locomotive decoder you are programming and has nothing to do with what system you are using. The manufacturer id is the value of CV8. Example: CV8=11 means the decoder was made by NCE. 

5. To learn more about a configuration variable (CV) and how to change them with an NCE system read this article:

6. It is always a good idea reboot your system and the decoder after a factory reset. Some decoders might not be completely reset until the power is removed and restored. Similar to rebooting a PC after it is updated.


MFG ID 8 - Broadway Limited (BLI)

 - must be done using POM / Programming on the Main / OPS mode 

Reset CV8 = 8

To use ops mode programming / POM you must disable voice read back, to do this Set CV62=0 to turn off

mfg id 101 - Bachmann sound decoders / Soundtraxx Tsunami
try setting cv 8 to value of 8
tsunami can only program short address on program track
to identify a decoder as a Tsunami - function 3 , is short whistle
mfg id 11 - NCE factory reset CV30 to value of 2
cv1= short address, default is 3
cv29= default is 6 which is: short address, factory speed table, 28 steps, dual mode on,
cv19 =0   disables consisting
MFG ID – 151 Loksound (ESU)  
Reset   CV8 = 8
The ESU Loksound V4.0 & Select decoders use a multiplier factor of 0.25 rather than the NMRA standard factor of 0.896 for the values of Acceleration (CV 3) and Deceleration (CV 4) rates. This means that you will need to enter a value nearly 4 times as great (3.6) in the Acceleration and Deceleration CVs to achieve the same rate as in a LokSound V3.5 or almost any other brand of decoder. This can be a problem with the NCE Momentum button, particularly if you have V4.0 (or Select) and other model decoders in the same consist.
mfg id 127 Lenz
lenz decoders   -tilt loco for 7 seconds to reset decoder
- Atlas / lenz   reset   set CV8   value 33     
mfg 113 QSI  - must be done using POM / Programming on the Main / OPS mode 

 - must be done using POM / Programming on the Main / OPS mode 

Sometimes have background noise
Set CV23 and CV24 to 0   to disable momentum
QSI locos might have a reed switch and magnet wand to turn on.
Generally requires Programming Track Booster like a soundtraxx PTB100- Do NOT use a DCC Specialties PowerPAX! To use ops mode programming / POM must disable voice read back- Set CV62=0 to turn off
The Broadway, Atlas, and Lifelike equipped with QSI (ID 113) DCC sound engines use a different reset procedure. Check the manual that came with the engine. Some use a magnetic “wand” for the reset. If there is no "wand" then open the engine or access hatch and find the reset jumper. Remove the jumper and restore the track power. There will be an audible acknowledgment from the engine at the end of the reset sequence (usually 3 toots of the whistle/horn). Replace the jumper and test out using address 3. If a "wand" is present, locate the internal reset reed switch and place the "wand" over it for a moment. When track power is restored the engine will go through its reset procedure and let you know when done. To find the internal reset (reed) switch, place the engine on active track. Slowly move the "wand" over the top of the engine or tender until the engine alerts you, audibly responds, by a message.

QSI also has a software reset using the following multi step procedure:
(1) Place engine on main track if it is still responding to its address. If not responding you may need to use the program track.
(2) Set CV49 to 128
(3) Set CV50 to 255
(4) Set CV56 to 113 As engine resets you will hear the 3 toots.
Test out the locomotive using address 3.
QSI also has some selective resets.

To reset MTH to the address to factory default 3:

1. Set the engine on the main, enter loco number 55 into your cab, press enter

2. go into program on main / OPS ode programming 

3. program loco number 55,

4. set CV 55 with a value of 55.

exit out, tilt loco or reboot your entire system.
and call up loco 3,
perform start up by press F3 to start loco.

F7 to cycle thru 9 volume levels
F8 for smoke

A reminder that MTH decoders are primarily designed for the Proprietary MTH DCS system. This means that many functions and settings of an MTH loco might not be available under DCC.





Mfg. ID in CV8

CV for reset + value



CV8 = 33



CV30 = 2



CV8 = 8

LokSound (ESU)


CV8 = 8

Train Control System


CV8 = 8 


CV30 = 2

SoundTraxx: DSDLC, DSX Tsunami (1)


old - CV 30 = 2

newer - CV8=8

MRC (New) (2)


CV125 = 1

QSI (1)


See Below

(1) When used with the Power Pro / PH-Pro may need a Programming Track Booster like the Soundtraxx PTB-100 (2) Generally is not reliable in Read-Back.
