Shift Indicator: Description and Operation

The upshift indicator lamp is pulled to ground by the powertrain control module (PCM). When the lamp is pulled to ground, ignition voltage
flows through the lamp, allowing it to illuminate. This indicates when to shift to the next highest gear for maximum fuel mileage.
