Tried to perform the idle relearn in the "work mode'' After i hit start it said please wait may take upto 5 mins. Waited almost 10 mins nothing happened. tried again same thing. can you tell me what I am doing wrong . thank you.
Please visit our website www.x431.com, and select either Launch China or Other Area. Log in, and select the tab labled "Datums" at the top. Select Techincal Article and look for #9 Nissan - (1).HOW TO PERFORM IDLE AIR FLOW VOLUME LEARN
Pay attention to the requirements listed (ie operating temperature, wheels ahead, park brake, ALL LOADS OFF like AC etc. codes cleared) Also, if you have trouble getting the function to finish read the TSB's from Nissan on what to do to run the learn. This covers the Consult tool but is applicable to ours as well.
The TSB requires disconnection of one to three injectors to stumble the engine in order to initiate the process. You can also unplug the MAF for two minutes and run it in failsafe then reconnect. It should run the learn procedure.
If it still won't run, select acuations and see if you have control of the IAC. If not, fix that first.
Spot on info Coyote. Was having trouble with a re-learn on a 2005 Murano and by unplugging 2 injectors and then re-clearing trouble codes, the IAVL process was successful.
Just as a note, the Nissan TSB (NTB05-067 for reference) states that this is applicable to all 2002-2005 Nissan models.
