disconnect the battery for a few minutes
How do I reset the service engine light on a 2003 Chevy Trailblazer?
bring the truck to autozone and let them reset it with their scn tool for free.
why appear light ( service engine soon), after change oil on a 2001 ford pickup (f150)?
disconnect the battery for 1 minute and it will reset.
That requires an OBDII engine scanner to do that. But it will not do any good to reset it if you did not fix the problem that made it come on in the first place. It will just come back on. NEED to scan the engine to see whats wrong with the emmission system.
I reset the check engine light on my jeep by disconnecting it from the battery.
That requires an OBDII engine scanner.
I was told by a co-woker that if you disconnect the negative battery cable for about 20 minutes or so that will reset the service engine light.
unhook battery or scan tool will do it
disconnect the battery for 30 seconds
