Behind this panel on the passenger side

When you get to the section of the autozone site,their will be several different diagnostic modes to choose from,if you have the 2 mode system,use MODE II

If you have the 5 mode system,use MODE III

Mode II

SELF DIAGNOSTIC RESULTS (IGNITION ON)

In this mode, Diagnostic Trouble Codes (DTC's) can be retrieved from the ECM. The DTC is indicated by the flashing sequence from the MIL or the red LED on the ECM.

1.Turn the ignition switch ON, but do not start the vehicle.

2.Turn the ECM diagnostic mode selector fully clockwise for two seconds, then turn it back fully counterclockwise.

3.Observe the red LED on the ECM or CEL light for stored codes.
----------------------------------------------------------------------------------------------------
Mode III, proceed as follows:

Thoroughly warm the engine before proceeding. With the engine OFF, turn the ignition switch ON.

Turn the diagnostic switch located on the side of the ECM ON by either flipping the switch to the ON position or using a screwdriver, turn the switch fully clockwise.

Turn the diagnostic switch OFF or fully counterclockwise as soon as the inspection lamps flash three times.

The self-diagnostic system is now in Mode III.

When the battery is disconnected or self-diagnostic Mode IV is selected after using Mode III, all stored codes will be cleared. However if the ignition key is turned OFF and then the procedure is followed to enter Mode IV directly, the stored codes will not be cleared.

The codes will now be displayed by the red and green inspection lamps flashing. The red lamp will flash first and the green lamp will follow. The red lamp is the tens and the green lamp is the units, that is, the red lamp flashes once and the green lamp flashes twice, this would indicate a Code 12.
