Normal Operation
The performance shift indicator shares the SVT logo on the tachometer. The performance shift indicator is configurable on or off and uses engine rpm to determine when to illuminate. The performance shift indicator receives the engine rpm status from the powertrain control module (PCM) over the high speed controller area network (CAN) communication bus lines. When the engine rpm is equal to the preset (configured) shift rpm, the instrument cluster turns on the performance shift indicator.

Possible Causes
- PCM
- Instrument cluster
