Frequently Asked Questions
I have everything hooked up and the system will not respond.

When remote starting, the siren chirps 3 times and parking lights flash 3 then 1 time.

the CMX.
I am trying to program the control module with the OP500 Option Programmer and it flashes
“ER 01” when I plug it in to the antenna cable. What should I do?
A: Make sure that the system is not locked/armed. The last thing to check is the antenna cable or antenna
extension cable – make sure this is not damaged. If you need to, try another cable. When the OP500 is
working properly, it will read “success good.”
What is the green/white wire loop inside the brain module?
A: This wire determines the transmission mode. With the loop intact, the system is set for manual
transmissions. With the loop cut, the system is set for automatic transmission. If the loop is cut for a
manual and installed on a manual transmission vehicle the Warning: DO NOT CUT THE LOOP
FOR MANUAL TRANSMISSION VEHICLE Manufacturer or seller assumes no
responsibility for any injuries and/or damages caused by this improper conversion and
transform of the product done by a user voluntarily.
What do I do with the thick blue wire on Connector 1?
A: It is used to power a (+) 2nd Ignition. You can also change the output via jumper within the control module. It can be
changed to power a (+) 2nd Accessory or (+) Parking light wire.
I need a ground when armed wire, does the control module have one?
A: You can use pin 1-blue/white wire on the Grey Connector 5. 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 and it does not back feed to your
accessory. Install the stripe side of the diode facing the control module.
What do I do with the 6 Pin harness on Connector 3?
A: The 8 Pin harness on Connector 3 is used for low current ignition harnesses. DO NOT use this harness
with the Connector 1 Harness (the high current power harness) this is ONLY to be used in LOW current
applications where High current is not needed for any reason.
Does the CMX series have Tachless mode?
A: Yes. The CMX offers several “no connection” engine sense options. For details, review the “Common
Procedures” section of this manual, or feature 2-10 & 2-11 option descriptions.
