CONDITION

01 12 17 June 20, 2012 2029281 Supersedes T.B. V011216 dated May 25, 2012 to further explain enhanced pedal vs. standard pedal.

Shift improvements, and/or MIL illumination, and/or long engine cranking times while using E85, with or without "Enhanced Accelerator Pedal Operation".

NOTE: This bulletin only applies to vehicles built before March 15, 2012.

TECHNICAL BACKGROUND

NOTE: There will be two software packages to choose from. Both software updates will fix all symptoms/conditions listed. One will contain an enhanced accelerator pedal operation and one will not. Refer to the "Symptoms/Conditions" for a detailed description of the changes. Be sure to consult with the Customer on what software version they prefer, Enhanced Pedal or Standard Pedal. Once the software choice is programmed it is a permanent change. Vehicles built after Feb 1st, 2012 will only show the enhanced pedal as an available update.

NOTE: For unsold vehicles make sure that the Enhanced Pedal software is applied. DO NOT apply the Standard Pedal software to the unsold vehicles. The enhanced pedal feature only reduces accelerator pedal range and does not affect transmission shift points or fuel economy.

Customer may comment on one or more of the following symptoms:

Transmission

Harsh 1-3 Upshift while operating in Economy (ECO) mode.

Harsh 2-3 upshift while operating in normal mode.

There is another software choice available, in addition to addressing all the symptom/conditions listed. This new version of software, called Enhanced Pedal, has an update to the accelerator pedal operation. This change when applied, will make the vehicle more responsive, with less pedal input, and also take less effort to maintain a constant cruising speed. Be sure to consult with the Customer on what software version they prefer, Enhanced Pedal or Standard Pedal. Once the software choice is programmed it is a permanent change .

Driveability

Long crank times after an overnight soak when temperatures are between 14° F and 41° F (-10° C to 5° C). This condition is noticeable when E85 fuel is being used. Tugging or a fish bite sensation while driving down the road under a very light throttle at a steady state. This is most noticeable when temperatures are between 32° F and 86° F (0° C and 30° C).

MIL Illumination

Upon further investigation the Technician may find that any of the following Diagnostic Trouble Codes (DTC's) have been set:
