CAPONORD 1200
•
shorted to positive / shorted to negative, open circuit.
Error cause
•
If shorted to positive: excessive voltage has been detected at PIN 28 of the ENGINE con-
nector. If the circuit is open, shorted to negative: voltage equal to zero has been detected
at PIN 28 of the ENGINE connector.
Troubleshooting
•
If shorted to positive: disconnect the coil connector, set the key to ON, activate the coil with
the diagnostics instrument and check voltage at connector PIN 28: if there is voltage, restore
the cable harness; 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.

Error cause
•
If shorted to positive: excessive voltage has been detected at PIN 27 of the ENGINE con-
