Neutral Safety Switch Test
Neutral Safety Switch - Wiring Harness Disconnected (Appearance May Vary) Step 2 - Obtain a wiring diagram used to trace wires which enables continuity testing. This switch uses a simple grounding procedure to individual circuits when the switch is activated. Search Google images or an online service manual such as Mitchell1 to obtain such diagram.
Neutral Safety Switch Wiring Schematic.
Test Light Helpful Information The functionality of the neutral safety switch has changed greatly through the automotive development era, what was once a simple switch for the reverse lights and starter safety circuits, this switch has now become a multifunction gear position sensor which provides feedback data to the body and engine computers, all related functions are then carried through the operating system. The neutral safety switch disables the starter operation when the vehicles transmission is not in neutral or park, and are equipped on automatic transmission vehicles only. A standard transmission car utilizes and clutch safety switch in place of the neutral safety switch which accomplishes the same objective. When a neutral safety switch fails it can cause the starter or reverse lights not to operate. Other complications can occur if a loose connection exists near the wiring connector, confirm this connection by removing the connector and reconnecting it. Tools and Supplies
