How do you reset the maintenance required light on a 1992 Dakota 5.2L?
The maintenance light,You will need to take it to a Dodge dealer to reset it. Or get a DBR-2 code scanner.BIG $$$

I discovered this answer on a recent search (Mar2008), but print it and take it to the mechanic with you. After years of ignoring my light, my local…
