TUONO V4 R a-PRC ABS
unit will acquire the throttle valve position. Connect with the diagnostic tool and check that the states
of "Automatic throttle valve self-learning is "performed" and "Handle self-learning" is "Not per-
formed" (the latter involved the display of the message Urgent service on the instrument panel). If the
automatic throttle valve self-learning indicates "Not performed" go to step 1, if "Performed" is indicated,
go to step 2. Step 1: current errors were probably detected by the control unit: resolve the malfunction
and recheck the two states. Throttle self-learning can also be performed from the Parameter adjustment
screen page (screw driver and hammer). Step 2: perform handle self-learning from the Parameter ad-
justment screen page (screw driver and hammer) and check that the Handle self-learning state is
Performed. If not ok, either the voltage detected on the handle is out of scale (check using the diagnostic
tool) or current errors were detected by the control unit: resolve the malfunctions and repeat the pro-
cedure
