We have a GMC equipped with a Cat C-7 on rent . On the dash panel there is a light that says "Service Engine Soon". I assume this is the engine maintenance indicator. Having serviced the engine how is the indicator re-set..?
I went into the engine ECM with Cat ET but could not find anywhere to reset the maintenance interval timer.
