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.

Self Diagnostics Test
- The control assembly will detect electrical concerns occuring during the self-test.
- Ensure that the engine is warm, at least 120°F, coolant temperature.

To display the error codes for condition detection, initiate the self-test by pushing off and floor simultaneously and then auto within two 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 indicates no errors found.

- The Self Diagnostic 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. To exit the self-test and restart the system, push the blue button. The self-test should be deactivated before powering the system down. Refer to Dianostic trouble code chart.
