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 0.05 V on terminal 39 of connector 88V.NR of the injection ECU 1320 | control unit disconnected, ignition off, check: - resistance correct with the table of values between terminals 39 and 22 of connector 88V.NR - the continuity and insulation of wire(s) A, B |
Short circuit to positive or open circuit
| conditions under which the fault appears | checks conditions for checking |
|---|---|
| voltage greater than 4.95 V on terminal 39 of connector 88V.NR of the injection ECU 1320 | control unit disconnected, ignition off, check: - resistance correct with the table of values between terminals 39 and 22 of connector 88V.NR - the continuity and insulation of wire(s) A, B |
