My 2003 Chevy Cavalier
2.2 four cylinder
Check vehicle light
tip/donation yes
tech = jk
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.





JK:
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!
