ultra starter problems

Hi

I have a 2002 trailblazer I purchased it used a few years ago and it came with a Ultra starter already installed only reason i know this is the remote and there is a sticker under the hood warning about service mode.

I have never installed a remote and i recently brought to a friend who does install remotes and alarms because i am have alot of problems.

first problem I was having is the remote start would only work in the winter( that is ok i don't really need it in the summer) and as I was driving my horn would start beeping three times so i found out that was going into service mode because of a problem with the hood pin( I cannot find )

now my second big problem is that unit keeps just going off  with the lights and horn going off alomost like a alarm but from hat I was told there is no alarm installed I had the horn disconnected for the remote starter but my lights still go off and this on happens at night and the only way to stop it is to pull a fuse or drive the truck till the remote starts to kick usually after about 15 minutes

can anyone help me with or tell what i need to do to just stop it 

thanks     

Your problem only occurs when and after  you use the remote start? Try reseting the unit. Also double check and make sure the brake wire is tied in and test it with a meter.

I am having some difficulty in understanding the details of the second problem about it randomly going off at night.

the lights and horn(before it was disconnected) would  go off for no reason and i could not not stop it without pulling the fuse that controls the electric for the enitre vehicle

it is almost like a  alarm was set off or that the remote starter would go into panic mode and could not be turn off  

I hope that explains it better

did you get that hood pin fixed?

Do you have an owners manual for the unit....?

The LED should give you "some: info as to what zone was violated.

Look on the main unit under the dash and get yourself a copy of the owner's AND install manual HERE

i mwill look tonight when I get home so i can pull the dash off the see what model I have

Thank You for trying to help

I found the unit but all the part numbers are rubbed off all the unit say now is

PDL data

bypass for ast

but it looks like my unit might be a alarm and remote because there is a small led light on the unit which is not working
