•
Shorted to negative (upon key-ON)/Signal not valid.
Error cause:
If shorted to negative: on key-ON a voltage equal to zero has been detected at PIN 47. If signal is not
valid it means that the control unit has detected activation of the lever but not its release within the set
time limit.
Troubleshooting:
Indication on Navigator always ACTIVATED: disconnect the sensor connector and, with the switch
RELEASED, check if there is continuity between the two cables (PIN 1) and (PIN 2) (sensor side): if
present, replace the sensor; if not present, replace the cable harness. Disconnect the Engine connector
from the Marelli control unit and check the ground insulation of the black cable (sensor PIN 1 - Marelli
