New to the web site. Iam having issues with my 2004 dhs deville! Well here i go.... I recently purchased this vechile and iam having problems with my sensors go off. Brake,air bag,check engine lite,gas cap,and my temp gauge is acting weird. So i went and ran a diagnostic check,and the only thing that came up was fuel emissions... Oh and just last night my brake light icon came on. I check all these myself and my car is running fine and fluids r full. I NEED HELP! FIRST TIME OWNER SMH!

:welcome:

Did you get a low voltage code by any chance?
----------------------------
my thoughts exactly -

what is the voltage on the display with KEY-ON - ENGINE OFF?

what's the voltage with the engine running?

have you checked for codes with the on-board scanner -
or a hand-held ?
