Okay...Today shortly after installing my brand new subs/amp (By shortly i mean a good 5 hours or so) my check engine light came on. I'm not quite sure what the problem is but I am almost certain it has nothing to do with the stereo in any way. The car still runs fine but i'm going to take it to the dealer in the morning just to be certain. I'll post updates as my situation progresses

 

When you disconnect the battery in these cars it trips a code.

The code is P0603 KAM (Keep Alive Memory) PCM error

If it is this code, it will go away if you just start your car and shut it off a couple of times.

I hope thats all it is...

 

Oh okay, i'll try this out since the service shop is closed on the weekend
Thanks

 

my engine light came on yesterday.... its sitting here at the dealer i work for, awaiting the news...

its no different running, but the light is on!!!!!!!

 

haha sounds like we are in the same situation but I have to wait until Monday to see what the problem is.

 

mine is fixed...

once yet again, the ECU had to be reprogrammed...

mine through a catalytic converter code... a TSB was active on it for a reflash of the eeprom, and now the light is off...

good thing i work for a Chevrolet dealer!!!! good luck!

 

hey patrick, where in MD are you from???

if you installed a new head unit, it will trip the code. the factory head unit blelieve it or not controls a few things on the car. they are small and pointless, like the key chime, but with some emission standards the car wont pass with a check engine light on. so keep the old cd player. you might need it.

 

I've had the new head-unit in for about 2 weeks with no problems. It was only after I installed the subs and amp, after tomorrow i'll know what it is.

 

Well I took my car in today and waited for about 15 minutes for them to look at it. Turns out my car was throwing up a cataylic converter code or something like that. I hafta take it to them tomorrow morning and they are gonna run tests all day, I hope they wash it for me

 

I had this issue when I did my stereo install.

 

You should ask about the tsb Lucky 13 referred to in his post.

 

Right down your mileage to make sure they dont really run some tests on it!

 

The stereo controls NOTHING. Unplug your stereo and the chimes still work! Stereo install places will try to charge you for a "device that makes the chimes work", what for if they work with the stereo unplugged? its a SCAM if you ask me.

 

I will have to agree with him on this one. I lost nothing except the steering wheel controls when I installed the aftermarket head-unit.

 

i have a cat conv code as well...mckay chevy in fairfax (where i work) is trying a new cat on it...

 

According to the dealership the light came on because of "the gas going into the new exhaust system" or something like that. Now I have to take it back to repair a chip (10 inch long split) on the driver's side windshield that I got 2 minutes after receiving it back from the dealer.

EDIT: Pics!

Actual Invoice

Rock Chip

 

stores arent ripping you off... on most new GM cars if you unhook the stock deck you lose chimes... I did in my cavy
