Sentra L4-1.8L (QG18DE) SULEV (2003)
Step Three: Reprogram The ECM
Step Four: ECM Reprogramming "Wrap-up"
1.
Turn the ignition switch "OFF" and CONSULT-II "OFF".
2.
Wait more than 10 seconds, then:
a.
Turn the ignition switch "ON" for 2 seconds, then
b.
Turn the ignition switch "OFF" again for 10 seconds (see Figure 6). 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 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 it's still ON, use CONSULT-II with the Diagnostic (red/white) Card to erase any DTCs that may have stored during the reprogramming
procedure.
