Neutral Safety Switch: Testing and Inspection

Inhibitor Switch Testing:

1. Raise vehicle and support with safety stands.
2. Disconnect control linkage from manual shaft and disconnect inhibitor switch connector.
3. Check continuity across terminals as described on the accompanying chart.
4. If not correct, adjust inhibitor switch.
5. If correct, check or adjust selector lever and control linkage.

Inhibitor switch input voltage can be checked at ECU terminal 3D with ignition "ON." In "N" or "P" range terminal voltage should be 0V. In other ranges, voltage should be approximately 12V.
