CLEARING DTCS
CAUTION: When battery is disconnected, vehicle computer and memory
systems may lose memory data. Driveability problems may
exist until computer systems have completed a relearn cycle.
To clear DTCs using a scan tool, refer to owners manual
supplied with scan tool. If scan tool is not available, DTCs may also
be cleared by disconnecting negative battery cable or PCM for at least
15 seconds, allowing PCM to clear DTCs. Reconnect negative battery
cable and check for DTCs to confirm repair.

SUMMARY
If no hard DTCs (or only pass DTCs) are present, driveability\
symptoms exist, or intermittent DTCs exist, proceed to H - TESTS W/O
CODES article for diagnosis by symptom (i.e., ROUGH IDLE, NO START,
etc.) or intermittent diagnostic procedures.
TERMINAL IDENTIFICATION
NOTE: The following terminals are shown as viewed from component
side of connector. Vehicles are equipped with different
combinations of components. Not all components are used on
all models. To determine component usage, see appropriate
wiring diagram in L - WIRING DIAGRAMS article.
