Starter Relay

Starter Relay

If the vehicle has been successfully re-mobilised, the immobilisation ECU (C0059) provides a feed to the starter relay coil (C0576) on an RW wire. The relay coil (C0576) is earthed on a B wire. The energised relay allows a feed from fusible link 7 to flow across the relay switch contacts (C0572) to the starter motor (C0179) on an NR wire (NR then B on Td4 vehicles). For more details of starter motor operation, refer to the Charging and Starting – Td4 , Charging and Starting – K Series or Charging and Starting – KV6 sections of this manual.  CHARGING AND STARTING – Td4.  CHARGING AND STARTING – K SERIES.  CHARGING AND STARTING – KV6.

Diagnostic Socket

The diagnostic socket (C0040) is connected to the immobilisation ECU (C0059) by a K wire, enabling the immobilisation ECU to be interrogated by TestBook or T4.
