Without Scan Tool

PROCEDURE
A scan tool must be used to retrieve DTCs from the PCM memory. DTCs can no longer be retrieved by grounding terminals "A" to "B" at the Data Link Connector (DLC). This also eliminates the PCM function of flashing Code 12. The use of a Tech 2 scan tool or equivalent will be needed to obtain both current and history DTCs.
