NEW CONTROL UNIT ACTIVATION PROCEDURE and REPROGRAMMING
After installing the control unit for the first time, or after REPROGRAMMING the control unit with a
different or more updated mapping, turn the key to ON and wait 3 seconds; during this time the control
unit carries out throttle position acquisition. Connect to the diagnostics instrument and check that the
status for "Throttle self-learning" is "Carried out" and the status for "Handle self-learning" is "Not carried
out" (the latter status entails Urgent service being displayed on the instrument panel). If Throttle Self-
learning shows "Not carried out", go to stage 1. If it shows "Carried out", go to stage 2. Phase 1: current
errors have probably been detected by the control unit: solve these malfunctions and check the two
statuses. Throttle Self-learning can also be checked from the Parameter adjustment (screwdriver and
hammer) screen page. Stage 2: Carry out the Handle Self-learning from the Parameter adjustment
(screwdriver and hammer) screen page and check that Handle Self-learning status is Carried out. If not
OK the voltage detected on the throttle is out of scale (check with diagnosis instrument) or current errors
have been probably detected by the control unit: solve these malfunctions and repeat the procedure
