My 2003 Chevy Cavalier. 2.2 four cylinder.
Check vehicle light
Question = Hello. My 2003 chevy cavalier has the service vehicle light on. A wrench with the word
service on it. Also the odometer does not show any number, it says ERROR. Any help would be
great, thank

Thanks for the tip/donation. These symptoms you are describing sound like a problem in the BCM
(Body Control Module) The bcm sends the odometer reading to the dash cluster. Since it says
'error', the dash is not  receiving the correct data. The service vehicle light is on because of this
problem. To be sure,  you need to have the
BCM scanned for codes. If you find B1000, then the
BCM will need to be  replaced. I will send you instructions on how to do this if you are going to do
it yourself. Once  again, thanks for tip/donation.
