the ground insulation of the cable (from coil connector or control unit connector), if not OK,
restore cable harness.
Coil 3 P0353
•
shorted to positive / shorted to negative, open circuit.
Error cause
•
If shorted to positive: excessive voltage has been detected at PIN 2 of the ENGINE con-
nector. If the circuit is open, shorted to negative: voltage equal to zero has been detected
at PIN 2 of the ENGINE connector.
Troubleshooting
•
If shorted to positive: disconnect the coil connector, set the key to ON, activate the coil with
Navigator and check voltage at connector PIN 2: if there is voltage, restore the cable har-
ness; if voltage = 0, replace the coil.
•
If the circuit is open, shorted to negative: check electric characteristics of the coil: if not OK,
replace the coil, if OK check the coil connector and the Marelli control unit connector; if not
OK, restore, if OK, check cable continuity between 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 ground insulation of the cable (from coil connector or control unit connector), if not OK,
restore cable harness.
