Injection
Check the efficiency of the injection load remote
control: Check the resistance of the energising coil
between pins 86 and 85: 80 ÷ 120 Ohm.
Apply a voltage of 12V to pins 86 and 85; make
sure that there is continuity between pins 30 and
87 of the remote control.
Check the power supply line of the injection load
remote control energising coil: after switching the
line "ON", make sure there is battery voltage for
two seconds between the Green-Red cable and
the Black-Purple cable of the remote control base.
If there is none, check the continuity of the Green-
Red cable between the fuse box in the battery
compartment and the remote control base and of
the Black-Purple cable between pin 8 of the control
unit and the remote control base.
NOTE
CONTINUITY TESTS MUST BE CARRIED OUT WITH THE
COMPONENTS DISCONNECTED. (BATTERY, REMOTE
CONTROLS, CONTROL UNIT, FUSES, ETC.).
