2003 Chrysler Town & Country Question: Disconnect bcm to get better mileage?
I would like to know what the thinking is behind this. If you are getting poor mileage, there is an issue with the fuel/ignition system that needs to be resolved, and resetting the BCM is not a solution. Is your T&C getting poor mileage or do you just want better mileage? - Bret Bodas
No this may cause your car to loose its programing and this will be expensive to fix you want better milage check your tire psi, change the oil and get a tune up - sinautoscan.com
