2005-2015 ALL INFINITI MODELS; ECM REPROGRAMMING SERVICE INFORMATION
After ECM reprogramming, the Calibration Verification Number (CVN) needs to be automatically calculated prior to State emissions testing (also known as Inspection Maintainence, I/M, or SMOG testing depending upon location). Allowing the vehicle to idle for 22 minutes will allow for faster CVN calculation. It is recommended that customers utilize this method if the vehicle needs to be tested for emissions soon after ECM reprogramming.
-REVISED- 2011-2013 INFINITI QX56; WHINE NOISE FROM ENGINE AREA
A whine type noise is coming from the Bank 2 (B2) side of the timing chain system.
The noise is best heard from the high pressure fuel pump area.
The noise should increase in frequency with engine speed (RPM).
If the noise does not increase with engine speed, the timing chain system may not be the cause.
Refer to the appropriate section of the Electronic Service Manual (ESM) for further diagnosis.
