Principles of Operation: Notes
When installing a new instrument cluster, it is necessary to upload the module configuration information to the diagnostic tool. Following installation of the instrument cluster, download the module configuration information from the diagnostic tool into the new instrument cluster. For additional information, refer to MODULE CONFIGURATION . The following items are configurable:
- all wheel drive (AWD)
- compass
- anti-lock brake system/traction control/interactive vehicle dynamics (ABS/TC/IVD)
- low coolant warning indicator
- speedometer bias
- climate control type
- oil life threshold
- default language
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 ignition switch is turned to the ON position, the charging system, low oil pressure, and the malfunction indicator lamp (MIL) illuminate until the engine is started and operating normally.
Each time the ignition switch is turned from OFF to ON, the following instrument cluster warning indicators prove out:
- air bag (6 seconds)
- ABS (3 seconds)
- BRAKE (3 seconds)
- low coolant level (3 seconds)
- low fuel (3 seconds)
- low washer fluid (3 seconds)
- safety belt (60 seconds or until the safety belt is buckled)
- traction control (3 seconds)
- anti-theft (3 seconds)
- electronic throttle control (ETC) (3 seconds)
- check fuel cap (3 seconds)
