Displaying and Reading Diagnostic Trouble Codes

NOTE: Ford DOES NOT provide a procedure to retrieve or clear trouble codes. Code retrieval is integrated into the EATC Module Self-Test. Ford DOES NOT provide an alternate procedure for performing the Self-Test with an NGS or generic tester.

EATC FUNCTIONAL TEST
1. Perform the EATC Functional Test. Record all error codes displayed during the test.
2. The control assembly will detect electrical malfunctions occurring during the Self-Test.
3. Ensure the engine is warm (at least 49° C (120° F) coolant temperature).

TO INITIATE THE SELF-TEST
1. To display the error codes for the malfunction detected, initiate the Self-Test by pushing OFF and FLOOR simultaneously and then AUTOMATIC within two seconds. The test may run as long as 20 seconds, during which time the display will be blank. If the display is blank for more than 20 seconds, go to System Diagnosis When Self-Test and Functional Test indicate NO ERROR. When Self Test and Functional Test Indicate No Error
2. The Self Test can be initiated at any time with the resulting error codes being displayed. Normal operation of the system stops when Self Test is activated.

SELF-TEST DEACTIVATION
1. To exit self-test and restart the system, push the blue button. Self Test should be deactivated before turning off the system. Refer to the Error Code Key/Symptom Chart for an explanation of error codes.

Error Code Key/Symptom Chart:

NOTE: Refer to the Error Code Key in the chart for an explanation of error codes.

2. If the error codes appear during the EATC Functional Test, follow the diagnosis procedures outlined in the Symptom Chart for each error code recorded.
3. If a malfunction exists, but no error code appears during the test in Step 1, refer to Diagnosis When Self-Test Indicates No Error Found. Electronic Climate Control

NOTE: The in-vehicle temperature must be greater than 10° C (50° F) for all error codes shown to be valid.
