Ignition Switch Position Run/Start (ISP-RS)

WARNING: This page is about a different car, the 2007 Mercury Mariner and 2007 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.

The ISP-RS provides the PCM with a VBAT input signal from the ignition switch, indicating the key is in the START position.
