Electrical system
ignition switch is turned to "OFF" and it remains
active 48 hours so as not to damage the battery
charging process.
When the ignition switch is turned to "ON", it inter-
rupts the function of the Immobilizer lamp and a
start enable lamp comes "ON".
The duration of the flash depends on the program-
ming of the electronic control unit.
If the LED is off regardless of the position of the
ignition switch and/or the instrument panel is not
initiated, check if:
•
there is battery voltage
•
that fuse No. 1 and fuse No. 2 are in
good conditions.
•
there is power to the control unit as
specified below:
Remove the connector mounting bracket shown in
the photograph and disconnect the connector from
the control unit. Check the following conditions:
With the key switch set to OFF:
• there is battery voltage between terminals 7-9 and terminal 9-chassis ground (fixed power supply). If
there is no voltage check that fuse 2 and its cable are in working order.
With the key switch in the ON position:
• there is battery voltage between terminals 6-7 and terminal 6-chassis ground (fixed power supply). If
there is no voltage, check the ignition switch contacts, that fuse 5 and its cable are in working order.
After removing the leg shield back plate, remove
the electrical connection from the antenna as
shown in the picture.
