Checks to be carried out if fault is present
Short circuit to positive:
406
| conditions under which the fault appears | checks to be made conditions for checking |
|---|---|
| engine running, short circuit to positive on terminal(s) 43 (88 V.NR) | ignition on, engine management ECU disconnected, built-in systems interface disconnected; check: - no voltage on terminal(s) 43 (88 V.NR) - 1320 ignition injection control unit |
All models, not 406
| conditions under which the fault appears | checks to be made conditions for checking |
|---|---|
| engine running, short circuit to positive on terminal(s) 43 (88 V.NR) | ignition on; engine ECU, disconnected, instrument panel disconnected: check: - no voltage on terminal(s) 43 (88 V.NR) - 1320 ignition injection control unit |
Short circuit to earth
| conditions under which the fault appears | checks to be made conditions for checking |
|---|---|
| engine running, presence of earth at terminal 43 on the 88 V.NR connector | ignition off; engine ECU, disconnected: check: - no earth at terminal(s) 43 on the 88 V.NR (1320) connector |
Open circuit
| conditions under which the fault appears | checks to be made conditions for checking |
|---|---|
| engine running, open circuit on terminal(s) 43 (88 V.NR) | ignition off - check the continuity of the line, (terminal 43 of the ECU 1320 (88 V.NR) connector) |
