PZM Input Values
WARNING: This page is about a different car, the 1998 Cadillac Eldorado and 1998 Cadillac DeVille. However, it is still accessible from the selected car via links, so may be relevant.
PZM input selection provides testing of inputs to PZM. Input status is shown on display as HI or LO. Input test status is shown as "O" until PZM sees a transition in state of switch; status then changes from "O" to "X". This changing status can be monitored to check inputs.
