Signal Ground

CIRCUIT OPERATION
The signal ground circuit Z11 connects to cavity 47 of the Power Distribution Center (PCM). The Z11 circuit provides ground for the sensors that provide inputs to the PCM. Internal to the PCM, the signal ground circuit connects to PCM sensor return circuit (from circuit K4) and the power (device) ground circuit (Z12).

The termination point for Z11 is an eyelet attached to the left side of the radiator closure panel.
