There are some issues here:
- ESU decoders also need CV15/16 locking enabled (bit 1 of CV 124).
- TCS decoders treat CV15=0 as a "universal unlock key" for a decoder, irrespective of the value in CV16. Other decoders lock if CV15=0 and CV16>0.
See for more quirks.

My primary decoder is a Loksound Direct with all lights and the front motor connected to it. My secondary decoder is a TCS T1 for JUST rear motor control.
My primary decoder is programmed for decoder lock with CV16=2 and my secondary decoder is programmed for decoder lock with CV16=1.
Both decoders work fine and are brand new. Each decoder has separate track pick up wires wired to it, so decoder 1 picks up track power from the front trucks, decoder 2 picks up track power from the rear trucks.
When I program both decoders to the 4 digit loco address only the sound decoder will drive it's motors
When I assign the secondary decoder a separate 4 digit address and consist it with the first decoder, only the first decoder motor works.
CV15=0,1,2 depending on if I'm programming or not and which decoder I want to program.
