A customer reports experiencing a small speed fluctuation when in cruise control and traveling downhill.

ACTIONS:

Confirm this bulletin applies:

• Check and compare your Current ECM Part Number to Table A on page 6.

If that part number does not match one in Table A, this bulletin does not apply. Go back to
ASIST for further diagnostic and repair information.


If applicable, reprogram the ECM.

AND

If the vehicle is equipped with Intelligent Cruise Control (ICC), replace the ICC Distance Sensor

 

I'll try to remember to do this tomorrow, the download screwed up and now my 1 file per day allowance is all used up.

 

A link to the full TSB is now available in the FAQ sticky, thanks treacherous!
