ELECTRICAL ERRORS
H.V. Coil P0352 - shorted to positive / open circuit or shorted to negative.
Error cause
Shorted to positive: excessive voltage at PIN 8 of the control unit connector.
Circuit open or shorted to negative: interruption of the circuit or null voltage at PIN 8 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 3: 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.
