TCU diagnostics (POWER light and 16 blinks): how to perform correct diagnostics?

So I have read the steps to follow in order to do a TCU diagnostic from www.svx-iw.com:

"4.5.4 - Diagnostics

The "Power" light indicates transmission codes. The following self diagnosis will show any fault codes for the transmission.
To perform the self diagnostic test for EXISTING problems:

1. Warm up engine by driving at speeds greater than 12mph.
2. Stop vehicle and turn ignition switch OFF.
3. Turn ignition switch ON and make sure POWER indicator lamp comes on.
4. Turn ignition switch OFF.
5. Move selector lever to D and turn manual switch ON.
6. Turn ignition switch ON.
7. Move selector lever to "3" and turn manual switch OFF.
8. Move selector level to "2" and turn manual switch ON.
9. Move selector lever to "1" and turn manual switch OFF.
10. Partially depress accelerator pedal (to turn idle switch off).
11. Check code as displayed on POWER light. Blinking once every 1/4sec is normal.

To perform the self diagnostic test for PREVIOUS problems:

1. Warm up engine by driving at speeds greater than 12mph.
2. Stop vehicle and turn ignition switch OFF.
3. Turn ignition switch ON and make sure POWER indicator lamp comes on.
4. Turn ignition switch OFF.
5. Move selector lever to "1" and turn manual switch ON.
6. Turn ignition switch ON.
7. Move selector lever to "2" and turn manual switch OFF.
8. Move selector lever to "3" and turn manual switch ON.
9. Move selector lever to "D" and turn manual switch OFF.
10. Partially depress accelerator pedal (to turn idle switch off).
11. Check code as displayed on POWER light. Blinking once every 1/4sec is normal.

Trouble codes:

* 11 - Duty solenoid A
* 12 - Duty solenoid B
* 13 - Shift solenoid 3
* 14 - Shift solenoid 2
* 15 - Shift solenoid 1
* 21 - ATF temp sensor
* 22 - Atmospheric sensor
* 23 - Engine revolution signal
* 24 - Duty solenoid C
* 25 - Engine torque control signal
* 31 - Throttle sensor
* 32 - Vehicle speed sensor 1
* 33 - Vehicle speed sensor 2"


But I am missing something because I never get the codes. Is IGNITION ON as in the "ON" position or fully starting the car (which will not do if it's not either in NEUTRAL or PARK)? How would you clarify these instructions to get it right the first time? I am getting 16 warning blinks and I am trying to find out what's the problem. Thanks.

It means in the on position, not started.

you may have a bad transmission resistor. Check near the battery to see if it's plugged in.
Have you installed the small car shift kit?

No shift kit on this one. Original resistor plugged in (I also tried with a 25W, 15-ohm one). I will try to post a video on the behavior of it.
