ISSUE
Some 2007 Expedition and Navigator vehicles built before 12/22/2006 may exhibit concerns with the Instrument Cluster (IC). The outside air temp reads
140 °F (60 °C), message center switches unresponsive/text blank or scrambled, compass display is inoperative, washer fluid level light is on.
ACTION
Follow the Service Procedure steps to correct the condition.
NOTE
DO NOT REPLACE IC ASSEMBLY UNTIL COMPLETE DIAGNOSIS HAS BEEN PERFORMED.
SERVICE PROCEDURE
Check the build date code of the IC. The date code is displayed in the message center during "engineering test mod&'.
Engineering Test Mode:
1.
Ignition in "OFF" position.
2.
Cluster type.
a.
For Base Clusters (without message center cluster): depress the reset stem on the cluster while turning the ignition switch to the "ON"
position.
b.
Message Center Clusters: depress the reset button in the vehicle while turning the ignition switch to the "ON" position.
3.
Continue to hold down the reset stem/button for 5 seconds until the cluster message center displays "engineering test mode".
4.
Press/cycle reset stem/button until the message center displays "manufacture" and the date of manufacture (MM-DD-YYYY).
5.
If the date is after 12/22/2006, this TSB does not apply and proceed with normal diagnostics found in Workshop Manual (WSM), Sections 413-01
and 413-08.
6.
Turn the vehicle ignition to the "OFF" position to exit the "engineering test mode".
Outside Air Temperature (OAT) Diagnostics
NOTE
THIS PROCEDURE IS FOR VEHICLES WITHOUT (ELECTRONIC AUTOMATIC TEMPERATURE CONTROL) EATC.
1.
Run vehicle for 5 minutes.
2.
Verify the OAT reads 140 °F (60 °C) in the Message Center.
3.
Disconnect the OAT sensor.
4.
Does the Message Center still read 140 °F (60 °C)?
a.
Yes - proceed to Step 4.
