(Supersedes 10-073, dated November 24, 2010, to revise the information marked by the black bars and asterisks).
REVISION SUMMARY
* Under WARRANTY CLAIM INFORMATION, the flat rate time was changed because the MVCI updates control modules more efficiently.*
SYMPTOM
The driver feels an intermittent engine vibration when the vehicle is stopped and idling with various electrical systems on.
PROBABLE CAUSE
The PGM-FI software is slow to respond to engine load because of varying electrical loads.
CORRECTIVE ACTION
Update the PGM-FI software with the HDS.
SOFTWARE INFORMATION
HDS Software Version: 2.020.018 or later.
Control Module (CM) Update:
Database Update 29-NOV-2009 or later.
NOTE:
To avoid an incorrect repair that would not be covered under warranty, use the software version listed above or a later version.
The updated PGM-FI software program IDs and P/Ns are shown below. If the HDS is loaded with the latest software, and it displays No Update Needed during the update, the software for this service bulletin is already installed.
