Electrical system
•
Check the preload motor because it is likely to be mechanically locked, otherwise replace
the motor.
Error preload motor control open circuit C1621
Error cause
•
An interruption of the circuit has been detected.
Troubleshooting
•
Check the connector on the component and the VCU connector. Disconnect the two con-
nectors and check the continuity of the cable between the PIN 1 motor - PIN M2 VCU and
between PIN 2 motor - PIN M1 VCU. If the cable harness is not damaged, replace the motor.
Error acquisition travel limits preload motor C1701
Error cause
•
Failed memorisation of the travel limit positions of the motor: this occurs in case of first
ignition of the motorbike or following a reset of the VCU.
Troubleshooting
•
Carry out the self-learning procedure using the diagnosis instrument.
Error timeout search travel limits preload motor C1702
Error cause
•
Failed memorisation of the travel limit positions of the preload motor. The error occurs if,
after 2 minutes from the start of the acquisition procedure, the VCU cannot record the motor's
travel limits: possible interruption of the circuit.
Troubleshooting
•
Check the connector on the component and the VCU connector. Disconnect the two con-
nectors and check the continuity of the cable between the PIN 4 motor - PIN B2 VCU and
between PIN 6 motor - PIN A2 VCU. If all the above-mentioned tests have a positive out-
come, replace the motor.
Error connections preload motor C1703
Error cause
•
Inverted connections of the preload motor.
Troubleshooting
•
Check the connector on the component and the VCU connector. Disconnect the connector
of the component and ensure that PIN 1 and 2 are insulated between themselves. Discon-
nect also the VCU connector and check the continuity of the cable between PIN 1 motor -
PIN M2 VCU and between PIN 2 motor - PIN M1 VCU.
