V7 III ABS
•
Short-circuit to positive: excessive voltage at PIN 8 of the control unit connector
•
Open circuit or short-circuit to negative: interruption of the circuit or zero voltage at PIN 8 of
the control unit connector
Troubleshooting
Short-circuit to positive:
•
Disconnect the right coil connector, turn the key to ON and activate the component through
the diagnostic tool.
•
Verify the presence of voltage on the right coil connector PIN 3: if present, restore the wiring
harness, otherwise replace the right coil.
Open circuit:
•
Carry out the check procedure of the right coil and control unit connectors.
•
Verify continuity of the wiring harness between the right coil and control unit: Right coil PIN
3 - control unit PIN 8. In the absence of continuity restore the wiring harness.
•
Verify, with the key turned ON, the presence of voltage on the right coil connector PIN 1. If
no voltage is read, verify the continuity of the wiring harness between right coil and injection
loads relay (No. 28 on the electrical circuit diagram): Right coil PIN 1 - relay PIN 3.
•
If the above tests provided a positive result, the right coil should be replaced.
Short-circuit to negative:
•
Disconnect the control unit connector and the right coil connector.
•
Verify the right coil connector PIN 3 ground insulation (or control unit connector PIN 8). If
necessary, restore the wiring harness.
