Neutral Safety Switch Interface; Testing The Neutral Safety Switch - Directed Electronics Auto mate 552 Installation Manual

We suggest the following procedure to test for vehicles manufactured in this way.

NOTE: You must complete the remote start system installation before doing the following test.

Ensure that the remote start system is functioning normally. This includes connecting to the brake

as a shut-down.

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 will release 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 the follow-

ing text and diagrams for an alternative shut-down method which will prevent the starter from engaging. If the

vehicle is not a General Motors product or a Dodge Dakota pickup, please call DEI® Technical Support for an alter-

native shut-down method. Do not return the vehicle to the customer until this feature is properly installed!

Every vehicle built this way requires that the shifter be placed in park to remove the keys from the ignition. As

a result, it is possible to use the key-in-ignition sense switch to prevent remote starting if the keys are in the

ignition. The diagrams in this section illustrate how to accomplish this.

Diagram A applies to all General Motors vehicles at the time of publication of this guide. Diagram B applies to

all pre-1996 Dodge Dakota pickup trucks with 2.5 liter motors. This solution has one side effect - if the customer

inserts the key in the ignition with the driver's door open, the remote start system will shut down. If this inter-

face is used it is important to inform the customer to close the driver's door before inserting the key into the

ignition when the remote start is active. This will allow the customer to turn the key on and shut the remote

start down by pressing the brake without the key sense wire shutting down the unit prematurely.

In addition, you must connect a tan (+) shut-down input to the yellow wire on the relay satellite ribbon cable.

This prevents the remote start system from activating if the key is left in the "run" position. If your remote start

system only has one tan input, you must use diodes to isolate the ignition circuit from the brake switch input.

However, due to future manufacturer changes in vehicles, it is possible that this may not apply to all vehicles.

In addition, color variations are possible from model to model; make sure to test the circuit carefully. Please call

DEI Technical Support if you need assistance in making this interface.
