hi guys i'm new here but hope you can help me i recently purchased a 06 silverado 1500 ....great truck all kinds of power and comfoft....but the ck eng light is always on ..my question is how do i reset it ???? thanks frank

 

Get an OBDII reader

 

purchased a code reader , says no power to ecm , could this be a fuse ? or a new computer is needed ..even went to auto store and they checked also , said it could be a bad wire ????

 

post the alpha numeric code that has set. did your scan tool say "no communication with ecm"?

 

didnt say anything.

 

When this happens it is usually the fuse for the cigarette lighter. This fuse feeds the OBDII connector in the truck.

 

yeah .that was the problem the cig fuse ,,thanks for your help

 

Wow! Wiring the OBDII unit via the accessory plug? Way to go, General Motors. :-(

 

its actually a good idea. when the scan tool won't power up, you can quickly check the lighter socket as its close to the dlc connector plug in.
