'04 Corolla Compustar Problem

Hey everyone,

Small problem I've been having. It seems that my parking lights on my alarm dont seem to want to work. I used a multimeter, and tested the output of parking lights off of the brain, and there doesnt seem to be any voltage going through. I similarly checked the horn output, and it was putting out about 6volts. So I'm pretty sure the brain works great. Does anyone have any suggestions as this is kinda driving me nuts. Thanks.

Your alarm should have a polarity input wire that feeds the power or ground to your parking light when the alarm brain would flash the lights.  It sounds like you may not have that wire hooked to ground or power (depending on the need of your car).

Hope that helps!

If the output from the main harness doesn't have any voltage when you try to lock or unlock the doors then check the fuse on the wire. If it is good and there's no voltage , then use the GREEN / WHITE wire from CN2 of the Compustar and connect it to the GREEN / WHITE wire coming from the light switch. This is the low current (-) trigger for the Corolla's relay to activate the parking lights.
