Any GM Mech'*? Buddies S10 Service Engine soon @ 50k miles
Does anyone know if GM makes the SES light come on ..on a 2000 *-10 ZR2 at 50k miles?
I was thinking it may be for transfer case/ tranny fluids.
I have access to a OBD II scan tool....will that tell me ...and can I shut that light off with it..
The most common cause of a 4.3 (assuming it had the W or Z engine) SES light is a clogged EGR. This can be removed and cleaned with brake cleaner but you will need to have a new gasket. Check the codes first. These things have a lot of computer controlled electronics that can through a SES.
