COIL
Function
Allows generation of the electrical discharge on
the spark plug, with an increase of voltage.
Pinout:
1. Power from relay
2. Activation by control unit (control unit side PIN
1)
ELECTRICAL ERRORS
H.V. Coil
P0351 - shorted to positive / open circuit or shorted to negative.
Error cause
Shorted to positive: excessive voltage at PIN 1 of the control unit connector.
Circuit open or short circuit to negative:interruption of the circuit or null voltage at PIN 1 of the control
unit connector.
Troubleshooting
Short circuit to positive:
- Disconnect the coil connector, turn the key to ON and activate the component through the diagnostics
instrument.
- Verify the presence of voltage on the coil connector PIN 2: if present, restore the cabling, otherwise
replace the coil.
Open circuit:
- Carry out the check procedure of the coil and control unit connectors.
- Verify continuity of the cabling between the coil and control unit: Coil PIN 2 - control unit PIN 1. If there
is no continuity, restore the cable harness.
- Verify, with the key turned ON, the presence of voltage on the coil connector PIN 1. If no voltage is
detected, check that the cable harness between the coil and injection relay is not interrupted: PIN 1 coil
- relay.
- If the above tests provided a positive result, the coil should be replaced.
Short circuit to negative:
- Disconnect the control unit connector and the coil connector.
- Verify the coil connector PIN 2 ground insulation (or control unit connector PIN 1). If necessary, restore
the cable harness.
