Kingman Posted November 12, 2009 Share Posted November 12, 2009 That is the ECU, the dial turns it to normal and diagnostic modes, and the green flashing light is an indicator. When you check your codes, that light and a red light will flash in sequence for the diagnostic codes. There's a how-to in the garage. Link to comment Share on other sites More sharing options...
5523Pathfinder Posted November 12, 2009 Share Posted November 12, 2009 Yep, its the ECM. The lights are not just for displaying codes, when you are not in diagnostic mode, they are displaying the operation of your O2 sensor. when they flash back and fourth, thats good. Oh yeah, dont get it wet. Link to comment Share on other sites More sharing options...

5523Pathfinder Posted November 13, 2009 Share Posted November 13, 2009 Unless you have it protected, you let all the factory smoke out. Its a nasty beotch to get it back in too. Link to comment Share on other sites More sharing options...

Toby Posted November 15, 2009 Share Posted November 15, 2009 It's a bomb you have to keep your pathfinder over 55mph or else it will explode *insert cheesy line here* Link to comment Share on other sites More sharing options...
Day95 Posted November 15, 2009 Share Posted November 15, 2009 well i should have been dead a while ago. that was a bad night... actually for the drive home i could not go over 43, had to have over drive off and and random lights were flashing.... well long story short i have no more interrior carpeting (rino lined now) and im not sure but should i replace my MAF, iv had a lil bit of power loss that iv noticed. id add a pic or two but my camera was on my passenger seat...
