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 CONFIGURATION .
The following items are configured:
- Speedometer calibration
- Brake system (base, anti-lock brake system (ABS), ABS/traction control [TC])
- Door ajar
- Shift indicator lamp
- Daytime running lamps (DRL)
- Door ajar warning chime
- Overspeed warning chime
- Back-up warning chime
- Key in warning chime
- Security system
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 warning indicator, the low oil pressure warning indicator, and the malfunction indicator lamp (MIL) illuminate until the engine is started and operating normally. The safety belt warning indicator proves out for 65 seconds or until the safety belt is fastened.
Each time the ignition switch is turned from the OFF to the ON positions, the following instrument cluster warning indicators prove out for 3 seconds:
- ABS warning indicator
- Air bag warning indicator (6 seconds)
- BRAKE warning indicator
- Fail safe cooling warning indicator
- Low fuel warning indicator
- Traction control indicator
- Anti-theft indicator
- Check fuel cap warning indicator
- Wrench warning indicator
- Tire pressure monitoring system (TPMS) warning indicator
