b.

Turn the ignition switch "OFF" again for 10 seconds (see Figure E). This will reset ECM "Self learned" Data.

3.

Start the engine and check the idle speed.

^

If idle speed is too low, perform Idle Air Volume Learning (IAVL). See the appropriate Service Manual (ESM) for this procedure.

NOTE:

If the engine will not idle, hold the engine RPM at about 2000, then slowly bring it down to an idle. IAVL can now be performed.

4.

Confirm the engine is operating normally.

5.

Make sure the MIL is OFF.

^

If the MIL comes ON, use CONSULT-II with the Diagnostic (red/white) Card to erase any DTC's that may have stored during the
reprogramming procedure.
