Green coil pair (A/B) stepping out after a motor start.
| Chan#1 - (B) - Green/White |
| Chan#2 - (A) - Green/Black |

Looking at one side of each coil to check the phase and timing.
Just after a motor start with the IAC stepping out.
| Chan#1 - (C) - Blue/Black |
| Chan#2 - (A) - Green/Black |
|
 |
| Same scope setup as above (looking at both coils). These
single steps occurred a little after start up. |
 |
| Same setup (both coils) but this is the retraction that occurred
after the key was turned off. |

| Looking at the A and C pins on the motor connector. This is the
phase relationship to extend the pintle. |
|
| Still looking at the same pins. The pintle is retracting. |
