Reset the ecu Scoobypedia | Trusted knowledge for everything Subaru | Knowledge / ECU

Disconnecting the battery for an hour or so can do it but the above link is a definate way of resetting.

I always reset the ecu after fitting new sensors etc.

 

Hi mate thank you for your reply i disconnected the battery while i was fitting the idle control valve the battery was off for about 3 hours.

 

You will probably need to set it for your car, but first yo should give it a clean. At first take the plug off and take the two wee scews out and pull it off, it is magnetised so when it comes off i have seen small bits of metal sticking to it give it a quick clean put it back on connect plug but dont tighten the screws right up. start car and adjust it on the sliders get someone to sit in car and set it to 800rpm when the car is warm. if you cant set it take it rught of and clean the inside make sure the wee flap is movin freely. Hope this Helps..
