pink/yellow cable (looking at the cabling):
•
voltage 0 V with engine kill in STOP;
•
12V if engine kill in RUN.
Blue/Green cable (cable harness side): always voltage 12 V (with key on)
DIAGNOSIS
•
The engine does not start: disconnect the connector and check, with the switch set to RUN,
that there is continuity between the two grey/light blue and red/white cables (sensor side):
if absent replace the sensor; if present carry out the check procedure on the connector; if
not OK restore the cabling; if OK verify, with the key ON, the presence of voltage on the
blue/green cable (cable harness side); if absent, restore cabling; if present verify insulation
from ground of the red/yellow cable (cable harness side). If there is continuity with ground
connection, restore the cable harness; if it is OK, set the key to KEY OFF and check the
control unit connector; if it is OK, replace the Marelli control unit
•
Engine does not shut off with switch in "STOP": disconnect the connector and verify, with
the switch set to STOP, that there is continuity between the two grey/light blue and red/white
cables (sensor side). If present, replace the switch; if absent this means that, with the key
ON, the pink/yellow cable shorts to positive: restore the cable harness. If cable harness is
OK, replace the Marelli control unit
