It's the same all over.

Pretty much, to check if a double solenoid is getting the correct signals from the user code, watch the LEDs on the PCM.
For a Double Solenoid you should see:
  • Only one PCM LED lit for the two sets of wires leading to the solenoid
  • Activating the solenoid the other way should switch the LEDs (that which was On shall go Off, and that which was Off shall go On).
A Single Solenoid will only connect to a single PCM LED and it will either be On or Off when switching states.

If the PCM LEDs are operating incorrectly, then the use code is incorrect.
If the PCM LEDs are working as expected, then you might have the wrong voltage selected on the PCM (12 vs 24v), or there might not be >20psi at the solenoid pressure input.
