I have been having these weird issues with my 09..

(1) My Alarm randomly goes off for no reason..... -----> about 3 weeks

(2) My DIC keeps telling me that my trunk is open and its not.. ----> NEW

(3) I have Drivers Side Turn Signal Flashing too fast.. --->NEW

(4) My Drivers side amber doesn't stay lit except when on turn signal ----> 2 months

Only Accurate DIC issue I have is the Service Tire System thing..... I removed my TPMS sensors for new ones coming in a few days


I am not sure if all these are related or not.... but I took it over to my local GM and they were complete ******** to me...

So I was just looking for some light on this crap...

Only Electrical Mods I have is:

Full Pioneer Sound System (Well Grounded and Wired)

35w HID Projectors (Low Beam w/CCFLs)

LED Glow Interior Lighting (Again, Well Grounded and Wired)


Please Let me know if you have any experiences or clues on these issues

 

try replacing ur turn signal bulb. and maybe pcm fucked?

 

Its not the bulbs.... I changed them all.... Its weird,,, somedays it works other days it works other days it doesnt.... I am honestly thinking about replacing the entire headlight harness... What other symptoms could I get from a bad pcm???

 

no idea really but you shouldnt be able to get dic or alarm issues from a headlight issue. maybe check the wiring make sure the fuse box in the hood isnt effect no wires pinched from installing hids

 

Maybe your interior LED lighting is tapped into the wrong wires, your HIDs are wired wrong/bad connector, and your remote is finicky? I know I can sometimes not even touch the button and my alarm goes off. Its either the above or you have a few wiring harness wires that have been nicked. Also is this the factory pioneer system you installed? If so, you could have an issue with the install and the computer now thinks someones trying to steal your radio(anti theft) which would explain the alarm.
