Hello everybody!!!
Before few days, my h2 stoped working. On display is "Unknown driver", and it can not start engine, actually it start on a second and then turn off, (like immobilizer).
Central locking, el.windows, gauges, radio....does not working too!!


I checked all the fuses and no luck.

Please help.

 

Is there a dealer nearby? (GM) They would be the first to know what's going on. Unless you have a way to connect a code reader to it, not much we can do for you from here.

Best of luck

 

I actualy borrowed my friends tech 2 scanner and the scanner turns on but it doesn't read anything... this is not a good sign. please help

 

i am probably going to have to bring it to gm.. im just afraid on the price...

 

Pull the battery connection and let it sit for a while. Reboot that ****

 

i did it for 4 hours and still nothing. not sure what to try next.. it does have aftermarket remote starter but not sure if that went back after 6 years.

 

I'd lay money that your body control module took a ****... Just incase you missed it, these are the fuses that power the body control module.

 

IGN 0 poweres the Powertrain Control Module, check that also.

 

Although it could prevent it from starting, its not going to take out all these other components that are not working. Everything in the cab, windows, locks, seats, buttons on the dash are not like on old cars directly controlling their intended component. Its all data communications. Button sends signal to BCM, BCM sends signal to component. Which it actually lets you do some neat ****. For example some of the bypass modules for remote starts will read the outside temp, if its under say 40 degrees it will start your car and turn on the heated seat and window defrosters automatically.

Make sure you post what got you back up and running.

 

Your key lost its code...if you have a second key try that..otherwise you will wave to go to dealer and get your key reprogrammed .
