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 shorted to negative: interruption of the circuit or null voltage at PIN 1 of the control unit
connector.
Troubleshooting
Shorted 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 1: if present, restore the cabling,
otherwise replace the coil.
The circuit is open:
•
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 1 - control unit PIN
1. In the absence of continuity restore the cabling.
•
Verify, with the key turned ON, the presence of voltage on the coil connector PIN 2. If no
voltage is read, verify the continuity of the cabling between coil and injection relay (No. 34
on the electrical circuit diagram): Coil PIN 2 - relay PIN 3.
•
If the above tests provided a positive result, the coil should be replaced.
Shorted to negative:
