KEY IN SENSOR CIRCUITS:
If the vehicle you are working on does not have or you cannot locate the
ECM reference wire, there are two alternatives available. Although not
preferred, the vehicle Key In Sensor may be reconfigured to allow a margin
of safety and will prevent the vehicle with a Mechanical Neutral Start
Switch from starting in gear.
WE ADVISE
WHENEVER POSSIBLE. The following two circuits may be used only if
the above circuit is not available.
NOTE: When completing an installation using either of the following key in
sensor circuits, if the operator inserts the ignition key while the vehicle is
running under the control of the Remote Start, the vehicle will shut down.
This must be explained to the operator as it is in contrast to the normal
operation of a vehicle utilizing an electrical neutral start switch and is
inconsistent with the operators manual.
Additional information concerning Key in Sensor methods 1&2 are listed
below and should be reviewed before considering either alternative.
Method 1 will allow the safety required for the remote start unit and prevent
the vehicle from starting while in any gear other than Park or Neutral while
the key is in the ignition cylinder however, if the key is left in the ignition
switch and the door is left opened, the added relay will be energized
causing a 150mA drain on the battery.
Method 2 will allow the safety required for the remote start unit and prevent
the vehicle from starting while in any gear other than Park or Neutral while
the key is in the ignition cylinder however, the original factory key in chime
module will not alert the owner that the key has been left in the ignition
switch. In addition, this may also effect other warning tones such as the
light on reminder.
These situations should be carefully considered before altering the
vehicle's wiring and must be fully explained to the consumer.
