Re: Service Engine Soon light
The SES light comes on when the PCM sees a problem with any one of the systems it monitors or controls..could be emmissions,transmission or some other PCM controlled mechanical device.
What code did the dealer find?
I have encountered a few intermittant stalling Envoys/Trailblazers over the last year, unfortunately I didn't find a common problem with them...loose connections, failed parts..nothing to indicate a model specific problem
