Frequently Asked Questions
I have everything hooked up and the system will not respond.
A: The remotes need to be programmed. Review the “Common Procedure” section of this manual.
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.” You no longer need to program the remotes before the
OP500 will sync.
I need a (-)ground when armed wire, does the control module have one?
A: You can use the (-)ground when armed wire on CN4 that goes to the .er 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 won’t back
feed to your accessory. Install the stripe side of the diode facing the control module.
On the brain, how do I set the auxiliaries?
A: Auxiliary 1 through 4 are not defaulted on with the CM2500 so you must have an Option
Programmer (OP500) to change the outputs to provide an output of your choice. Secure auxiliary (option 2-07)
will prevent these outputs from triggering without doing query first. Please review the “Special Option Group”
programming section of this manual for more details.
The vehicle will lock and unlock but not flash the parking lights.
A: The system is in valet mode. See Valet mode section of this manual or the remote users guide.
Whenever I try to arm the vehicle, it chirps the siren 3 times and will not arm.
A: Check the hood and trunk trigger inputs.
Do the door locks flip flop in polarity?
A: No. You can use the DM700 for high current positive (+) locks, or the DM600 harness used for low current
600mA positive (+) locks.
