Checks to be carried out if fault is present
Not specified (short circuit to positive)
| conditions under which the fault appears | checks to be made conditions for checking |
|---|---|
| engine running | verify: ignition on, ECU connected: - presence of voltage: at terminal 18 of connector 35V.NR of the ECU 1320 warning: presence of voltage, for 2/3 seconds after the ignition has been switched on ignition on, ECU connected, injector(s) disconnected: - no voltage at terminal(s) 18 of connector 35V.NR 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 |
Check(s) to be carried out if no fault found
Ignition off, control unit disconnected, verify
- No earth at terminal 18 on the 35V.NR connector
- Continuity and insulation of wire(s)
- Resistance R of the injectors: 13 Ω ≤ R ≤ 16 Ω
Check that the injectors are not blocked mechanically (actuator test)
