The ability to view engine-operating data, such as oil pressure and coolant temperature, in digital form on the instrument panel has been a feature of Corvettes since 1984. Starting in model year 1992 (MY92), the C4 IP would even display limited diagnostic data relating to the car’s on-board computer systems. C5’s capacity to do that is significantly expanded. The new car has 11 computer “modules” that transmit diagnostics: Powertrain Control Module (PCM),Traction Control System (TCS, which combines traction control, ABS and, on cars built after 12/15/97, the optional Active Handling System), Real Time Damping (RTD), Body Control Module (BCM), Instrument Panel Cluster (IPC), radio, heating-ventilation-air conditioning (HVAC), Left Door Control Module (LDCM), Right Door Control Module (RDCM), Seat Control Module (SCM) and Remote Function Actuation (RFA). The IPC display, the 20-character, vacuum-fluorescent screen above the steering column that says “Corvette by Chevrolet” every time you start the car, is a powerful device.
