FEED CIRCUIT OF THE DECODER AND THE FUEL INJECTION CONTROL UNIT
1 Check that circuit feed is constant
The basic feed on the decoder is necessary for the management of the blinking deterrent light. The feed on the
injection control unit is necessary for the management of the stepper motor.
The lack of basic feed inhibits both ignition and fuel injection.
In the case of a feed problem, diagnosis tester n° 020460Y gives the information “THE CONTROL UNIT DOES NOT
RESPOND”.
To carry out controls proceed as follows:
Check if the immobilizer system LED signals that it is set to “ON” and if the blinking
deterrent light is present.
The decoder is
being fed correctly
Set to "ON" with the side stand raised and
The emergency switch in the “OFF” position.
Illumination of the fuel injection indicator is provided
for approx. 3 seconds.
Check the digital
instrument and its
feed
Set the emergency switch to "RUN".
The fuel injection indicator lights up for approx. 5
seconds.
