Shift Up
The shift up telltale is turned ON by the cluster when it receives a command from the powertrain control module (PCM) (L61) engine. The shift up telltale indicates to the operator of the vehicle when to shift to the next highest gear for maximum fuel mileage.
The shift up telltale will be turned ON by the cluster for 2-3 seconds, when the ignition is turned to RUN, for a visual system check.
