How to Bypass the Neutral Safety Switch for an Automatic Transmission

A Neutral Safety Switch is a safety device found in cars and other motor vehicles that prevents the engine from being started unless the transmission is in neutral or park. It also prevents inadvertent shifting of the transmission into reverse while the vehicle is moving forward. Bypassing the Neutral Safety Switch for an automatic transmission involves wiring a relay to a switch, which then bypasses the NSS and allows the engine to start regardless of the position of the transmission. This can be done for various reasons such as in racing applications where you may want to launch from a lower gear, or if your Neutral Safety Switch has malfunctioned and needs to be bypassed while you replace it.

What is a Neutral Safety Switch?

A neutral safety switch is an important component of an automatic transmission vehicle. It prevents the car from starting in gear, which could cause it to unexpectedly lurch forward or backward when the ignition is turned on. The switch is designed to ensure that the car is in park or neutral before the engine can be started. It also ensures that the vehicle can only be shifted out of park when the brake pedal is depressed.

Function of the Neutral Safety Switch in an Automatic Transmission

The neutral safety switch contains two components that work together to prevent accidental starting of the engine in gear. The first component is a physical switch, typically located near the shifter, which reads whether or not the transmission shifter has been placed in park or neutral. If it has been placed in either of these positions, then it will allow power to flow through it to engage the starter motor and begin cranking the engine.

The second component of the neutral safety switch is an electrical circuit breaker which prevents power from reaching the starter motor unless both components are triggered at once. This means that even if someone tries to bypass one part of this system and directly apply power to engage the starter motor, it will not work unless both components are triggered correctly.

Location of the Neutral Safety Switch

The location of a neutral safety switch can vary depending on make and model, but they are usually found near or attached to a vehicle’s transmission shifter. On some vehicles they may also be located on or near steering columns; however, this is becoming increasingly uncommon as most newer vehicles now feature electronic shifters instead of mechanical ones with cables and levers associated with them.

Diagnosing Problems with the Neutral Safety Switch

When diagnosing problems with a neutral safety switch, there are several common symptoms you should look for: difficulty starting your vehicle; erratic shifting behavior; or an illuminated check engine light when trying to start your car. Additionally, if you’re attempting to bypass your neutral safety switch you may find that no matter what position your transmission shifter lever is set at, your car simply won’t start – this usually indicates that your neutral safety switch has failed and needs replacing.

Symptoms of a Faulty Neutral Safety Switch

If you experience any difficulty starting your car, especially if it won’t start even when in park or neutral position; erratic shifting behavior; or an illuminated check engine light while trying to start your car – these may all indicate a faulty neutral safety switch and should be checked by a professional mechanic as soon as possible.

How to Diagnose Problems with the Neutral Safety Switch

In order to diagnose problems with your neutral safety switch, you will need to first check for any visible signs of damage such as broken wires, loose connections or corroded terminals on both ends of its wiring harnesses – all these things could potentially cause problems with its operation and should be addressed immediately if found during inspection. Additionally, you should also use an ohmmeter (or multimeter if available) and check for continuity between each terminal/connection point on both ends – this will help determine whether there are any shorts between them which could potentially cause problems with operation too.
