Self-Diagnostic System: Notes
NOTE:
PCM diagnostic memory is retained by direct power supply from battery. Memory is not erased by turning off ignition, but it will be erased if battery or PCM is disconnected.
Self-diagnostic system monitors input and output signals through the Data Link Connector (DLC). Diagnostic Trouble Codes (DTCs) can only be read using a scan tester. For additional information, see TESTS W/CODES - 2.0L - NON-TURBO article.
