•
If shorted to positive: disconnect the coil connector, set the key to ON, activate the coil with
Axone and check voltage at connector PIN 1: if there is voltage, restore the cable harness;
if voltage = 0, replace the coil
•
if the circuit is open, short circuit to negative: check the coil connector and the Marelli control
unit connector. If they are not OK, restore; if everything is OK, check cable continuity be-
tween the two cable terminals. If there is not continuity, restore the cable harness; if there
is cable continuity, with key set to ON, check the cable earth insulation (from coil connector
or control unit connector). If it is not OK, restore the cable harness; if it is OK, check if there
is voltage in the red/brown cable, with key set to ON or activating with Axone. If there is no
voltage, check continuity and earth isolation of the red/brown cable from the coil connector
to the auxiliary injection relay connector 29. If it is not OK, restore; if everything is OK, dis-
connect the relay and check if there is voltage in the orange/red cable: if there is voltage,
replace the relay; if there is no voltage, check continuity and earth insulation of the orange/
red cable from the relay connector to the auxiliary fuse box and replace the cable harness.
Left coil (front cylinder) P0352 - shorted to positive / open circuit, shorted to negative
Error cause
•
If shorted to positive: excessive voltage has been detected at PIN 10 of connector A
(BROWN).
•
If the circuit is open, short circuit to negative: voltage equal to zero has been detected.
Troubleshooting
•
If shorted to positive: disconnect the coil connector, set the key to ON, activate the coil with
Axone and check voltage at connector PIN 1: if there is voltage, restore the cable harness;
if voltage = 0, replace the coil
•
if the circuit is open, short circuit to negative: check the coil connector and the Marelli control
unit connector. If they are not OK, restore; if everything is OK, check cable continuity be-
tween the two cable terminals. If there is not continuity, restore the cable harness; if there
is cable continuity, with key set to ON, check the cable earth insulation (from coil connector
or control unit connector). If it is not OK, restore the cable harness; if it is OK, check if there
is voltage in the red/brown cable, with key set to ON or activating with Axone. If there is no
voltage, check continuity and earth isolation of the red/brown cable from the coil connector
to the auxiliary injection relay connector 29. If it is not OK, restore; if everything is OK, dis-
connect the relay and check if there is voltage in the orange/red cable: if there is voltage,
replace the relay; if there is no voltage, check continuity and earth insulation of the orange/
red cable from the relay connector to the auxiliary fuse box and replace the cable harness.
