Checks to be carried out if fault is present
Short circuit to earth
| conditions under which the fault appears | checks conditions for checking |
|---|---|
| voltage below 0.1 V on terminal 68 of connector 88V.NR of the injection ECU 1320 | ECU connected, ignition on, check: - presence of voltage between 0.2 and 1.6 V on terminal 68 of the 88V.NR connector on the ECU control unit disconnected, ignition off, check: - insulation of wire B |
Short circuit to positive or open circuit
| conditions under which the fault appears | checks conditions for checking |
|---|---|
| voltage greater than 4.75 V on terminal 68 of connector 88V.NR of the injection ECU 1320 | ECU connected, ignition on, check: - presence of voltage between 0.2 and 1.6 V on terminal 68 of the 88V.NR connector on the ECU - the continuity and insulation of wire(s) B |
Consistency with accelerator pedal sensor 1
| conditions under which the fault appears | checks conditions for checking |
|---|---|
| check: - voltage on terminal 15 approximately double the voltage on terminal 68 of connector 88V.NR (injection ECU) | check: - voltage on terminal 15 approximately double the voltage on terminal 68 of connector 88V.NR - the continuity and insulation of wire(s) (terminals 15/68 of connector 88V.NR) |
