Frequently Asked Questions / Troubleshooting
I have everything hooked up, but the system still doesn’t do anything.
The remotes need to be programmed. The remotes for CompuStar systems do not
come programmed. This is because the CompuStar systems are modular in design
and the remotes are packed right before shipping the units out.
What wires do I need to hook up?
That all depends on what vehicle you are working with and what you want the
system to be capable of. There is no set answer for this question.
What is the green/white wire inside the brain module?
This wire determines the transmission mode. See page 7.
Where do the blue and purple wires off this extra relay go? (CM3000/CM3200)
This is a pre-wired positive output, negative trigger relay. See page 18,
‘Connector 2’.
Which parking light output do I use?
If you have a positive parking light circuit, then use the positive parking light
output, pin 2 of connector 1. If you have a negative parking light circuit, then use
the negative parking light output, pin 1 of connector 2.
What is the status output used for?
This is an optional output that will provide a (-) negative output before the
ignition is triggered during remote start, and will shut down after ignition has shut
down. (Note: This wire can be used to trigger factory security interface modules
and clutch bypasses.) Also known as a Ground While Running. (GWR)
I need a ground when armed, where can I get it?
You can use the starter kill output that goes to the starter kill relay. You must cut
this wire and place a diode in line so that when the ignition on the other side of
the relay goes to ground, it cannot back feed to your accessory. Have the stripe
side of the diode facing the CompuStar module and attach your accessory on the
CompuStar side of the diode.
Is the system Voltage Sensing?
No. You must have the engine sensing wire from connector 2 connected to either
a tach source or the alternator. See page 14.
How many times should the parking lights flash or siren chirp when I press the tach
learn button?
Once, see page 14.
