Neutral Safety Switch Interface; Testing The Neutral Safety Switch - Directed Electronics 4103, 4-button series Installation Manual

Neutral safety switch interface

Some vehicles do not have an electrical neutral safety switch, but instead have a mechanical neutral safety
switch that interrupts the starter wire when the vehicle is in any drive gear. The remote start must be interfaced
before the neutral safety switch , to provide protection from starting in gear. However, some vehicles combine
the column shift and the neutral safety switch into one mechanical part, and in this case you will not be able
to interface the remote start before the neutral safety switch.
Important: You must complete the remote start system installation before doing the follow-
ing test. Ensure that the remote start system is functioning normally. This includes connect-
ing to the brake as a shut-down.

Testing the neutral safety switch

1. Make sure there is adequate clearance to the front and rear of the vehicle because it may move slightly.
2. Make sure the hood is closed and there are no remote start shut-downs active.
3. Set the emergency brake.
4. Turn the key to the "run" position, this releases the shifter.
5. Place the car in drive (D).
6. Place your foot directly over the brake pedal, but do not depress it. Be ready to step on the brake if the
starter engages.
7. Activate the remote start system.
8. If the starter engages, immediately depress the brake to shut the remote start system down. If the
starter does not engage, no additional safety
system is required.
If the starter engages and the vehicle is a General Motors product or Dodge Dakota pickup, refer to
www. for Document 1008 under the Resource tab. For an alternative shut-down method

which prevents the starter from engaging. If the vehicle is not a General Motors product or a Dodge
Dakota pickup, please call Directed Electronics Technical Support for an alternative shut-down method.
Do not return the vehicle to the customer until this feature is properly installed!
