Calibrate rpm sensor


This function is used to teach in new calibration values to the control unit after work has been done or if the inductive rpm sensor has been replaced (See procedures in service manual). Before adjusting, the adaptation values shall be reset with the function "Resetting self-adaptation parameters".

After calibration, fault code ”P1300 Phonic wheel adaptation” may appear. To erase the fault code the diagnostic instrument must first be disconnected. Engine temperature must be above 85 °C and rpm should be above 5,500 rpm 3-5 times. Press down the accelerator pedal until the engine rpm is above 5,500 rpm and then release the pedal and let the engine go to idle.
