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 | verify: - ignition on, ECU connected: - no voltage at terminal(s) G2 of the control unit 32 V.GR warning: presence of voltage, for 2 to 3 seconds when the ignition is turned on ignition on, ECU connected, injector 2 disconnected: - 13 Ω ≤ R ≤ 16 Ω at the injector terminals 3 - 12 V absent on terminal G2 of connector 32 V.GR (computer) warning: if 12 V is present for 2/3 seconds after switching on the ignition, short circuit with a function supplied by +ve after relay |
Short circuit to earth
| conditions under which the fault appears | checks to be made conditions for checking |
|---|---|
| engine running | verify: - ignition off, control unit disconnected: - no earth at terminal G2 on the 32 V.GR connector (computer) |
Open circuit
| conditions under which the fault appears | checks to be made conditions for checking |
|---|---|
| engine running | verify: - ignition off, control unit disconnected: - continuity of wire(s) A correct - injector 1333 disconnected - injector resistance 13 Ω ≤ R ≤ 16 Ω |
Check(s) to be carried out if no fault found
Check that the injector is not physically sticking (actuator test)
