| Diagnosis and Testing Refer to Wiring Diagrams Section 419-10, for schematic and connector information. Principles of Operation The following warning indicator light emitting diodes (LEDs) are mounted in the information and message center: - Ice (amber)
- Low washer fluid (amber)
Ice Warning Indicator The ice warning indicator is controlled by the information and message center and the outside air temperature sensor. When the outside air temperature drops below 5°C (41°F), the information and message center illuminates the ice warning indicator. Washer Fluid Level Warning Indicator The washer fluid level warning indicator is controlled by the washer fluid level switch which is directly wired to the information and message center. The information and message center will activate the warning indicator when insufficient water is in the reservoir. The information and message center has the following functions available when the ignition is in position II: - Outside air temperature
- Average vehicle speed
- Instantaneous fuel economy
- Average fuel economy
- Range
For additional information, refer to the Owner's Guide. Inspection and Verification - Verify the customer concern by operating the system.
- Visually inspect for obvious signs of mechanical or electrical damage.
