- Short circuit to positive or open circuit
- Consistency with brake switch
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 15 of connector 88V.NR of the injection ECU 1320 | ECU connected, ignition on, verify: - presence of voltage between 0.5 and 3.35 V on terminal 15 of the 88V.RN connector on the ECU ignition off, control unit disconnected, verify: - insulation of wire A |
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 15 of connector 88V.NR of the injection ECU 1320 | ECU connected, ignition on, verify: - presence of voltage between 0.5 and 3.35 V on terminal 15 of the 88V.RN connector on the ECU - the continuity and insulation of wire A |
Consistency with brake switch
| conditions under which the fault appears | checks conditions for checking |
|---|---|
| simultaneous operation on the accelerator and the brake | verify: - mechanical operation of the accelerator pedal sensor - continuity and insulation of wire E - setting of the brake sensor |
