Odometers
Important: When replacing a speedometer/odometer assembly, the federal law requires the odometer reading of the replacement unit to be set to register the same mileage as the prior odometer. If the same mileage cannot be set, the law requires that the replacement odometer be set to zero, and a label be installed on the driver's door frame in order to show the previous odometer reading and the date of replacement.
Season and trip odometer displays are provided in both the base and uplevel clusters. The base level cluster uses a dedicated display for odometer information. The uplevel cluster displays odometer information on the DIC. The uplevel cluster also has 2 trip odometers. Season and trip odometer information are displayed in the DIC when the ODO/TRIP button is pressed. All calculations for these displays are made in the instrument cluster based on the vehicle speed input received from the PCM.
| • | Season odometer displays the total accumulated miles or kilometers of the vehicle. This value is permanently stored in the EEPROM of the instrument cluster. If an odometer malfunction occurs, or if the instrument cluster needs to be replaced, contact an authorized Delco® service center to program the proper vehicle specifics (including mileage) for the instrument cluster. |
| • | The trip odometer displays the accumulated vehicle miles or kilometers, since the last reset. This value is stored in KAM of the instrument cluster. |
| • | Press the TRIP RESET button in order to reset the trip odometer on the base instrument cluster. |
| • | Press the ODO/TRIP button in order to reset the trip odometer on the uplevel instrument cluster (UB7). The trip odometer messages are displayed on the DIC. Then press the RESET button. |
| • | The trip information displays in DIC. |
| • | If a button is not used to reset the trip odometer, the display rolls over automatically. |
The trip odometer rolls over at 999.9 miles when operated in English mode and at 999.9 kilometers in metric mode.
When the trip odometer displays greater than 621.4 miles (operating in English mode) and the ENG/MET button is pressed, the trip odometer resets to zero, since the conversion from miles to kilometers is greater than 999.9 kilometers. If the ENG/MET button is pressed again, the instrument cluster converts the displayed kilometers to miles.
