Electrical system
•
shorted to positive: disconnect the coil connector, set the key to ON, activate the coil with
Navigator and check voltage at connector PIN 3: if there is voltage, restore the cable har-
ness; if voltage = 0, replace the coil. Open circuit, shorted to negative: check the coil
connector and the Marelli control unit connector. If not OK, restore; if everything is OK, check
cable continuity between the two cable terminals. If there is no continuity, restore the cable
harness; if there is cable continuity, with key set to ON, check the cable ground insulation
(from coil connector or control unit connector). If not OK, restore the cable harness.
Rear coil P0352- shorted to positive / open circuit, shorted to negative.
Error cause
•
If shorted to positive: excessive voltage has been detected at PIN 19 of the ENGINE con-
nector.
•
If the circuit is open, shorted to negative: voltage equal to zero has been detected at PIN 19
of the ENGINE connector.
Troubleshooting
•
Shorted to positive: disconnect the coil connector, set the key to ON, activate the coil with
Navigator and check voltage at connector PIN 3: if there is voltage, restore the cable har-
ness; if voltage = 0, replace the coil.
•
If the circuit is open, shorted to negative: check the coil connector and the Marelli control
unit connector. If not OK, restore; if everything is OK, check cable continuity between the
two cable terminals. If there is no continuity, restore the cable harness; if there is cable
continuity, with key set to ON, check the cable ground insulation (from coil connector or
control unit connector). If not OK, restore the cable harness.

Throttle body

THROTTLE BODY
Function
To inform the throttle control unit the position of the
two throttle valves and to drive them both.
Operation / Operating principle
All the unit internal components (potentiometer
and electric motor) are contactless; therefore, no
electrical diagnosis is possible for the throttle
body, only for the circuits connected to it.
Throttle body activation takes place every time the key is set to ON: correct activation is indi-
cated when the stop lights turn on.
