DIAGNOSTIC TOOL: ACTIVATIONS
Lower injector cylinder 1
•
The injection relay (No. 33 in the electrical circuit diagram, placed under saddle, right side;
CHECK, however, the identification of the relay with the colour of the cables) is energised
for 5 seconds and the injector cable connected to control unit is closed to ground for 4 ms
per second. Disconnect the 4-way connector of the fuel pump to be able to hear the relay
and injector activation. Electrical continuity is required in the wiring for the relay to activate
correctly: no errors are generated if the relay fails to activate
