Circuit/System Verification
- Ignition ON.
- Verify the scan tool Ambient Air Temperature parameter is between -40°C (-40°F) and +88°C (+190°F) and changes with air temperature changes.
- If not between -40°C (-40°F) and +88°C (+190°F) or changes with air temperature changes
Refer to Circuit/System Testing .
- If between -40°C (-40°F) and +88°C (+190°F) and changes with air temperature changes
- If not between -40°C (-40°F) and +88°C (+190°F) or changes with air temperature changes
- Perform the Instrument Cluster Ambient Air Temperature Instant Update special function with the scan tool
- Verify the scan tool Ambient Air Temperature parameter is within five degrees of actual ambient air temperature.
- If not within five degrees of actual ambient air temperature
Refer to Circuit/System Testing .
- If within five degrees of actual ambient air temperature
- If not within five degrees of actual ambient air temperature
- All OK.
