ECU information available
Actuators test: yes
Parameter measurements: no
Characterised by
- Short circuit between two wires
- Open circuit or battery too weak or harness resistance
- Internal fault related to the control unit
Checks to be carried out if fault is present
Short circuit between two wires
| conditions under which the fault appears | checks conditions for checking |
|---|---|
| excess current between terminals 3 and 31 of connector 88V.NR | control unit disconnected, ignition off, check: - insulation of wire(s) A, B - resistance R = 0.56 Ω (maximum) between terminals 3 and 31 of the 88V.NR connector |
Open circuit or battery too weak or harness resistance
| conditions under which the fault appears | checks conditions for checking |
|---|---|
| none | check: - charging circuit - the continuity and insulation of wire(s) A, B - resistance R = 0.56 Ω between terminals 3 and 31 of the 88V.NR connector |
Refer to the procedure: check ECU function
