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
Answer: 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.
