Principles of Operation: Notes
When installing a new instrument cluster, it is necessary to upload the module configuration to the diagnostic tool. Following installation of the instrument cluster, download the module configuration from the diagnostic tool into the new instrument cluster. For additional information, refer to MODULE COMMUNICATIONS NETWORK . The following items are configurable:
- speedometer
- outside air temperature
- compass
- anti-lock brake system (ABS)
- anti-lock brake system/traction control (ABS/TC)
- overspeed warning chime
- reverse warning chime
- flex fuel
- overspeed trip point
- seatbelt indicator timeout
- electronic automatic temperature control (EATC)
- seatbelt chime
The instrument cluster contains an analog speedometer, tachometer, fuel gauge and engine coolant temperature gauge. The instrument cluster receives the information over the controller area network (CAN) circuits. The instrument cluster carries out a display prove-out to verify that the warning/indicator lamps and monitored systems are operating correctly. When the key is turned to the ON position, the charging system, low oil pressure and the malfunction indicator lamp (MIL)/check engine illuminate until the engine starts.
Each time the ignition switch is turned from OFF to ON, the following instrument cluster warning indicators will prove out:
- air bag (6-second prove-out)
- ABS (3-second prove-out)
- BRAKE (3-second prove-out)
- charging system
- check engine (MIL)
- low fuel
- low oil pressure
- safety belt (60-second prove-out)
- traction control (if equipped) (3-second prove-out)
- THEFT (3-second prove-out)
- check fuel cap (3-second prove-out)
