have it scan tested for codes when they have the scanner hooked you clear the codes and the light will go out but if it has any codes in the light will likely come back on
Thankyou for your reply i dont have a scanner just wondered about disconecting batt for 10min or so thanks
if you disconnect the battery the light should go out but like I said before if its got a code the light will come back on good luck
You can get it to go off by disconnecting the battery cables. But as GoodGuy stated, if it has a code, it will come back on.
