ELECTRICAL ERRORS
Fuel pump relay P0230
- shorted to positive / shorted to negative / open circuit.
Error cause
Shorted to positive: excessive voltage at PIN 22 of the control unit connector.
Shorted to negative: null voltage at PIN 2 of the injection relay.
The circuit is open: interruption of the circuit.
Troubleshooting
Shorted to positive:
•
Disconnect the injection relay (No. 35 on the electrical circuit diagram), turn the key to the
ON position and activate the relay through the diagnostics instrument.
•
Verify the presence of voltage between relay connector PIN 1 and 2 toward the cabling.
•
If no voltage is read, disconnect the control unit and verify insulation from battery positive
of the relay PIN 1 (or control unit PIN 22). Restore the cabling if necessary.
Shorted to negative:
•
Disconnect the injection relay (No. 35 on the electrical circuit diagram) and the control unit.
•
Verify ground insulation of the relay connector PIN 1 and 2 toward the cabling: if there is no
insulation, restore the cabling.
The circuit is open:
•
Disconnect the injection relay (No. 35 on the electrical circuit diagram) and the control unit.
•
Verify continuity of the cabling between the relay and control unit: Relay PIN 1 - control unit
PIN 22. Restore the cabling if necessary.
