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.

HOW TO USE THE SYSTEM CONCERN INDICATION/SELF-TEST FEATURE
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).

SELF-TEST INITIATION
1. To display the error codes for the malfunction detected, initiate the self test by pushing OFF and FLOOR simultaneously and then AUTO 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 the Self Test is activated.

SELF-TEST DEACTIVATION
1. To exit the self-test and restart the system, push the COOLER button. The Self Test should be deactivated before turning off the system.

Error Code Key:

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

2. If error codes appear during the EATC Functional Test, follow the diagnosis procedures outlined in the Error Code Key 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. Diagnosis When No Errors Found
4. The program code level can be accessed by simultaneously pushing the OFF and FLOOR button, then the OUTSIDE button within two seconds.

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