This issue is caused by a conversion error in PTT. It has been determined that the calculated value is correctly displayed, but the value that is programmed is incorrect. Solution Prior to performing any steps below, ensure that PTT is the current version. At the time of this solution's composition, PTT version 2.6.70 is the current release. The conversion error will be fixed in a future release. If a newer version is available, PTT should be updated and the issue confirmed to still exist prior to proceeding. A. Calculate the Vehicle Speed Factor 1. Run PTT Operation 3829-08-03-06 Vehicle Speed Factor, located under the Calibrate tab. 2. Enter the Drive axle ratio and Tire revs / mile as required 3. Press the Play button in the Step 1 box on the left-hand side of the screen. The Calculated Value box will display the Speed Factor. This value is correctly calculated. 4. DO NOT PRESS PLAY IN THE STEP 2 BOX. Copy or record the value displayed in the Step 1 box, then exit the Operation. B. Program the Calculated Value 1. Run PTT Operation 1700-22-03-03 Parameter Programming, located under the Program tab. 2. Once parameters have loaded, search for or locate parameter MH, Vehicle Speed Factor US. 3. Enter the value that was copied or recorded in Part A as the new value for parameter MH. 4. Complete the parameter programming operation to save the new Vehicle Speed Factor value.
