Neutral safety switch interface

Some vehicles do not have an electrical neutral safety switch. Instead, the vehicle has a mechanical neutral
safety switch that physically interrupts the starter wire and is used when the vehicle is in any drive gear. If the
remote start is interfaced before this switch, it will provide protection from starting in gear. However, some
vehicles combine the column shift mechanism and the mechanical neutral safety switch into one mechanical
part.
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!

Remote Start Shutdown/Startup Diagnostics

Shutdown diagnostics: If the remote start activates but fails to stay running, the remote start module has the
ability to inform you of what may have caused the remote start failure. Before performing shutdown diagnos-
tics it is important that you let the remote start shut off on its own i.e. let it attempt to start 3 times then shut
down, if this is not done the unit will report the shutdown you used to shut off the remote start.
Note: Shutdown diagnostics does not report if the vehicles factory immobilizer is causing the problem.
To perform shutdown diagnostics:
1. With the ignition Off, press and hold the Control button (on Control Center).
2. Turn the ignition On and then back Off while holding the Control button.
3. Release the Control button.
4. Press and release the Control button. The status LED flashes to report the last shutdown for one minute or
until the ignition is turned on, as shown in the following table:
