Checks to be carried out if fault is present
Short circuit to positive
| conditions under which the fault appears | checks to be made conditions for checking |
|---|---|
| engine running | ignition on; engine management control unit, disconnected, injectors 1 connected: - no voltage at terminal(s) 27 of the control unit ignition off; engine management control unit, disconnected, injector(s) 1 disconnected: - check the insulation of wire A1 in relation to wire B - check: resistance R of the injector between 15 and 17 Ω |
Short circuit to earth
| conditions under which the fault appears | checks to be made conditions for checking |
|---|---|
| engine running | ignition off; engine management control unit, disconnected, injectors 1 connected: - no earth at terminal(s) 27 on the 88 V.NR connector |
Open circuit
| conditions under which the fault appears | checks to be made conditions for checking |
|---|---|
| engine running | ignition on; engine management control unit, connected, injectors 1 connected: - check: presence of 12 V at terminal(s) 27 on connector 88 V.NR - check: resistance R of the injector between 15 and 17 Ω |
