Scan Tool Data Definitions: Data

WARNING: This page is about a different car, the 2003 Chevrolet Corvette. However, it is still accessible from the selected car via links, so may be relevant.

Console Switch Illumination: The scan tool displays 0-100%. The illumination percentage varies based upon the dimming switch information sent by the IPC on the serial data line. When the dimming switch is rotated to bright, the console switch illumination percentage will increase. When the dimming switch is rotated to dim, console switch illumination percentage will decrease. The headlamps or parklamps must be ON to read console illumination data.

DRL Ambient Light Sensor: The scan tool displays 0-5.0 volts. The voltage level varies based upon the ambient light level at the sensor. When light levels are high (Light), voltage will increase. When light levels are low (Dark), voltage will decrease. The BCM uses this information for automatic headlamp operation.

Fog Light Illumination: The scan tool displays 0-100%. The illumination percentage varies based upon the dimming switch information sent by the IPC on the serial data line. When the dimming switch is rotated to bright, the fog light switch illumination percentage will increase. When the dimming switch is rotated to dim, fog light switch illumination percentage will decrease. The headlamps or parklamps must be ON to read fog light illumination data.

HVAC Bulb Illumination: The scan tool displays 0-100%. The illumination percentage varies based upon the dimming switch information sent by the IPC on the serial data line. When the dimming switch is rotated to bright, the HVAC illumination percentage will increase. When the dimming switch is rotated to dim, HVAC illumination percentage will decrease. The headlamps or parklamps must be ON to read HVAC illumination data.

PRNDL Illumination: The scan tool displays 0-100%. The illumination percentage varies based upon the dimming switch information sent by the IPC on the serial data line. When the dimming switch is rotated to bright, the PRNDL illumination percentage will increase. When the dimming switch is rotated to dim, PRNDL illumination percentage will decrease. The headlamps or parklamps must be ON to read PRNDL illumination data.

Door Switch Pad Illumination: The scan tool displays 0-100%. The illumination percentage varies based upon the dimming switch information sent by the IPC on the serial data line. When the headlamps or parklamps are ON, and the dimming switch is rotated to bright, the LH door switch illumination percentage will increase. When the dimming switch is rotated to dim the LH door switch illumination percentage will decrease.

Door Switch Pad Illumination: The scan tool displays 0-100%. The illumination percentage varies based upon the dimming switch information sent by the IPC on the serial data line. When the headlamps or parklamps are ON, and the dimming switch is rotated to bright, the RH door switch illumination percentage will increase. When the dimming switch is rotated to dim the RH door switch illumination percentage will decrease.
