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 On Board Diagnostics Test
1. Record all diagnostic trouble codes (DTCs) displayed during test.
- The control assembly will detect electrical malfunctions occurring during the on-board diagnostic.
- Ensure that the engine is warm (at least 49°C [120°F]) coolant temperature). To display the DTCs for the malfunction detected, initiate the on-board diagnostic 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 General A/C System Diagnosis When On-Board Diagnostic Test Indicates NO ERROR.
- The On-Board Diagnostic Test can be initiated at any time with the resulting DTCs being displayed. Normal operation of the system stops when on-board diagnostic is activated. To exit the on-board diagnostic and restart the system, push the BLUE button. Pushing the DEF button instead of the blue button will clear all DTCs. The on-board diagnostic should be deactivated before turning the system OFF Refer to the DTC chart for an explanation of DTCs.
2. If a malfunction exists but no DTC appears during the test in Step 1, refer to the appropriate symptom(s) in the Symptom Chart. Electronic Climate Control
