How To Test Shift Interlock Solenoid

When it comes to safety, nothing is more important than ensuring that your equipment is in working order at all times. That’s why it’s so important to test shift interlock solenoids (SISs) on a regular basis. Not only do SISs help ensure that your machines are operating correctly, but they can also prevent accidents and injuries. In this blog post, we will walk you through the simple steps necessary to test your SIS. After reading this article, you will be able to appreciate just how important it is to keep your equipment in good working order!

What is a Shift Interlock Solenoid?

A shift interlock solenoid is a safety mechanism used in some vehicles that prevents the vehicle from starting if the driver has not shifted their gear into the appropriate gear slot. In most cases, this mechanism requires the driver to depress a button before they can start the car.

How Do I Test It?

To test your shift interlock solenoid, you’ll need to remove the air filter and the top cover of the transmission. You will also need a voltmeter, a screwdriver, and a socket wrench.

1. Disconnect the negative battery cable.
2. Remove the air filter and top cover of the transmission.
3. Connect the voltmeter to one terminal of the shift interlock solenoid fuse block and to ground (the metal body of the car).
4. Turn the key to ON position and start engine. The voltage should be low because current is being diverted from the fuse block to ground by the solenoid. If voltage is high, something is wrong with solenoid or wiring connection. Check for broken wires or bad connections at fuse block and solenoid terminals.
5. reconnect negative battery cable and remove all tools

What to Do If It Fails

If the shift interlock solenoid fails to activate your vehicle’s automatic transmission, there are a few things that you can do to troubleshoot the problem. First, try engaging the manual transmission and see if the problem persists. If the manual transmission still does not work, you may need to replace the shift interlock solenoid.
