TURN INDICATORS
If the blinker warning lights do not work, continuity
must be checked on the cable R-B between terminal 7
of the switch connector and terminal 9 of the dash-
board connector.
R.P.M. SENSOR
Engine rev information on the dashboard arrives by
means of a CAN line; therefore, if this information is not
displayed and the message CAN ERROR appears on
the dashboard, the problem can be attributed to the
dashboard.
STARTER RELAY ACTIVATION
• With the engine cut-off switch in the RUN position, press
and hold down the starter button and check if 12V is sup-
plied between relay switch wires B/Y and O/Y.
• If that is not the case, check if voltage is present
between the B/Y wire and ground
• If there is no voltage input , check the condition of
fuse E5 after which check the right hand control as
follows:
1) Disconnect the connector of the right hand con-
trol.
2) With the engine cut-off switch in the RUN posi-
tion, check for continuity between pins (
2 ) and ( 5 ),
and then check for continuity between contacts ( 1 )
and ( 3 ) while pressing the starter button.
3) If the right-hand control is in good working order,
the problem is due to a malfunction in the engine
control unit and its connections.
