c16,, code on rrm 16..may i asked you,this model is ac motor or not,and this model can be program using by a CAN KEY??? if it is that is easy 1st insert the can key to can bus and goto parameter 38 and set it to 1 and off the machine and turn it again on..remember do not press the accelarator pedal once you calibrate the machine..thank you i hope you solve it asap thank you and regards

Code CO16 indicates: Voltage from accelerator pedal's potentiometer R1 is outside the calibrated value at start up.
(+/-0.2V).
Check nothing is restricting accelarator from returning to neutral position.
