Control Harness (All wires are the smaller 18 AWG size)
9. Violet Wire Hood Pin Switch Control Harness
The hood pin switch MUST be installed with the AutoCommand®. It
prevents operation of the AutoCommand® when the hood is open. Connect
the VIOLET wire to the hood pin switch
using the red connector.
Note: If you already have a hood
pin switch which is being
used by a car alarm sys-
tem, you may share the
wiring -- but be sure
to diode isolate each
wire going to the
hood pin switch
with the bands
of diodes
pointing to-
wards the
pin switch
as fol-
lows:
10. Orange Wire Brake Shut-off
The ORANGE 18 gauge wire will disable the AutoCommand® when the brake
pedal is pressed down. This is an added anti-theft safety feature. This connec-
tion is usually made under or behind the brake pedal linkage at the switch.
Connect the ORANGE to the wire that receives +12 volt only when the brake
pedal is pressed down. Any +12 volt input on this wire will shut off the Auto-
Command®. In some cars, the ignition must be on to see the power at the brake
wire. This wire must be hooked up. This is a critical safety feature. This hook-
up is also required for other options discussed later.

20. Trouble Shooting with the Self Diagnostics
The AutoCommand® contains a built in diagnostic routine that will indicate
why the unit turned off the car the last time that the unit was used. To activate
the diagnostic mode, simply turn the On/Off control switch to the "OFF"
position. In a few seconds, the red LED on the module will flash 1 to 6 times
to identify the problem. See the chart below for an explanation of the flashes:
1 flash 10/15 minute time out -- unit should be fine.
2 flashes Brake or Hood activated
3 flashes No Tach or Stalled. Check tach learning. Or confirm that the
alternator is being powered up by one of the ignition wires.
4 flashes Received another remote input signal.
5 flashes Transmission was shifted into gear.
6 flashes Low battery voltage, or may be missing an ignition wire
which powers up the alternator
8 flashes Over-current. A transistor output is being over driven.
12 flashes The control switch was turned off.
In order to get an accurate diagnostic, allow the unit to go through its complete
starting cycle(s). The unit may only try to start once or it may try 3 times. In
order to get an accurate reading, please wait 45 seconds after its last attempt to
start.
21. Special Programming Options
®
The AutoCommand unit has 8 special options and features. You will not
need to use these special options in most situations. The factory settings will
operate most vehicles. You must turn the On/Off control switch to the "OFF"
position to program any features. Note that when turning off this control
switch, the red LED will flash a few times, giving the diagnostic code described
in Section 20. Wait a few seconds for it to finish before programming your new
