What steps do I need to take to replace my computer and various components?

Hi, have had my Cruze for 1 year now and love it, but I seem to be having a problem with the auto lights. Sometimes the dash lights up but sometime it does not and have noticed via friends my running lights dont go on. Should I take to dealer or am I doing something wrong? Thank you

So for the past year or so I have noticed that my car will throw the lights signaling me to service my traction control and also the stability track. This only seems to happen after where I live at has had a lot of rain. Also, my RPM gauge will no longer read and the arrow sits at 0. This always...

I call it the Pi3oneer, lol. I'm using Pioneer's cheapest model screen ( with a GMOS-045 to keep onstar and original color screen ). I'm using a Raspberry Pi3 micro computer to talk to the Cruze's ECU via an OB2 Bluetooth adapter. I plan to program my own software so I can see boost and mph via...

i had one of the trip screens going from new, the other reset every fill. went to check my lifetime trip info, and it was reset :shocked:

I know the DIC has quite a few messages programed into it, but I was shocked to see that it will tell you that your turn signal is still on...anybody else ever see that message.

I have had my Cruze now for 15 months. Bought it used in almost perfect condition with 32000 miles. I now have 55+ thousand miles. And since I bought it, every time I fill it up, and check the numbers, the trip computer says X gallons used, which varies anywhere from almost a gallon to...

I own a 2011 cruze lt. I got a recall from gm to up date my on board computer or emc module. I took into the dealer and had it done. I now have cruze that eats gas. I lost any where from 15 to 20 percent of my gas mileage. I could get from 7 to 8 lt in city driving. It now runs from 15 and up...

Anyone know if this may be covered? I just returned from the dealership getting my ECM -- Engine Control Module recall completed. Turns out when the battery isn't strong enough the recall procedure actually fries the ECM. My car currently has 89,000 miles on it (which is still under the...

while in Miami I had to do some emergency stops since its Miami and drivers suck. now I did a stop from 30 mph with foot down to the floor, I let off some 25% brake input and to my surprise the pedal stayed down on the floor and the car kept stopping without me giving the command...has this...

Does anybody know if there is a handheld (or even PC based software) that I can buy so I can do some of the "dealer only" things on my own? One for example is a DPF manual regen if I ever need to have one again. I also want to read and clear codes, but that part is easier. I am more...

Hey everyone, I hope this is a decent place to post this, but I wasn't able to find much on this by searching (Only this one referring to some Acton devices). I'm looking for details on what computer GM uses to diagnose their cars. I used to own a Smart Fortwo, and Mercedes has their Star...
