compustar 2wfmas CM3000

I have 2wfm installed about 4 years ago. today, i took a trip out of town when i got back the compustar did not response to my remote. i then tried to reprogram the compustar with the turning on/off and that didn't work. i have tried with the backup remote without the LCD display and that failed to work. the valet mode to turn on/off (I+III) and that didn't work.

i have probed with a DMM on the CM300 red(+), red/white and black(-) wires. all 3 wires show connectivity. i pulled out the hardness and plug it back after the probing but i did not probe from the hardness. should i have probe from the hardness? because there is no respond from the alarm i did not probe anywhere else. i don't know how to probe the antenna. does anyone know how? i have already pulled out the antenna hardness and replug it back-in in both sides.

i have pulled out the 2 fuses 30 and 10 or 15. both seems to be intact. both fuses don't have fuse number on it but it is 1 red and 1 green. what is the next step to troubleshoot this alarm. thanks.

it might be a bad brain. Good thing they have a lifetime warranty on them.

Just make sure you did the turn the key on and off 5 times and on the 5th time leave the key on and hit lock wait till stuff clicks and flashes if the park lights are hooked up then turn the key off.

I installed and own several compustars when installed right you rarely have problems.

It sounds like you have a bad antenna (the one on the windshield)...
