I have a 2001 3500 Heavy Duty Series 5.9 liter; Maint Reqd light came on @ 60K miles; Already checked all emissions control items and all seems to be working. I know this is the reason why the light comes on as scheduled @ 60K miles. Trying to find either a post or topic related to turning off the light. In the Chilton Manual it specifies that dealer must turn off. Are there any other options or suggestions to turn of the light myself?

 

You can reset the computer or I had the local Autozone store check the codes and eliminate the codes free.

 

went to auto zone and had scanner hooked up. but could not erase maint reqd light. scanner is only good for check engine light.those are the only codes you can erase. by the way no codes came up when it was scanned. does anyone have any ideas to turn the light off. thanks

 

I think you can disconnect the negative terminal on the battery and that will reset the computer, works for a "check engine" light.

 

first thing i tried was disconnecting the battery. did not work.
