Remove the connector support bracket shown in
the photograph and disconnect the connector from
the control unit. Check the following conditions:
With the key switch set to OFF:
•
if there is battery voltage between ter-
minals 6-26 and terminal 6-chassis
ground (fixed power supply). If there is
no voltage check that fuse 1 and its ca-
ble are in working order.
With the key switch in the OFF position:
•
there is battery voltage between termi-
nals 5-26 and terminal 5-frame earth
(fixed power supply). If there is no volt-
age, check the key switch contacts,
that fuse no. 10 and its cable are work-
ing order.
•
There is continuity between terminals
12-18 with the emergency cut-off
switch in the RUN position. If there is
no continuity check the contacts of the
switch.
If no faults are found, replace the electronic control
unit.
Virgin circuit
When the ignition system is not encrypted, any key will start the engine but limited to 2000 rpm. The
keys can only be recognised if the control unit has been programmed properly. The data storage pro-
cedure for a previously not programmed control unit provides for the recognition of the master as the
first key to be stored to memory: this becomes particularly important because it is the only key that
enables the control unit to be wiped clean and reprogrammed for the memorisation of the service keys.
The master and service keys must be used to code the system as follows:
- Insert the Master key, turn it to «ON» and keep this position for two seconds (lower and upper limits
1 to 3 seconds).
