Air Bag Light Still On After Repair (2014 SRX) Problem Solved!

A 2014 Cadillac SRX with a new sensor and module won't permit configuration due to codes not clearing. The L.F. door impact sensor and Air Bag Module were replaced. However, there are codes for the L.F. Impact Sensor and L.F. Door Sensor that won't clear, although sensors are good.
In order to clear the codes we must first find the root cause of the problem. First, using a Pico Scope, we compare the module communication to both front impact sensors. We could see that the signal was good to both sensors, but the module didn't like what it saw from the left front.
So, zooming in on the waveform told us that the signatures sent to each sensor by the module was identical. Knowing this, by using a Micro Amp Clamp, which can see current as low as 100 mA, we looked at the current draw on a known good sensor (R.F.), observing what a good pattern looks like. Moving to the left front, we can see that there's no current flow through the circuit. How is this possible when the sensor is brand new? Watch to the end to see what we found!
