Principles of Operation: Notes
When installing a new instrument cluster, it is necessary to upload the module configuration information to the scan tool. Following installation of the instrument cluster, download the module configuration information from the scan tool into the new instrument cluster. Refer to MODULE COMMUNICATIONS NETWORK article.
The following items are configurable:
- All wheel drive (AWD)
- Compass
- Anti-lock brake system/traction control/stability assist (ABS/TC)
- 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, the low oil pressure, and the malfunction indicator lamps (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)
- Wrench indicator (3 seconds)
- Check fuel cap (3 seconds)
