If several errors are present, they are displayed every 3 seconds.
Having concluded all the rrors, the milometer is displayed once again.
If the codes differ from those mentioned above, bear in mind that the first figure or letter identifies the
component, whilst the second figure identifies the type of fault, namely:
1. Open circuit - 2. Short circuit to earth - 3! Short circuit to + battery - 4. Short circuit and open circuit
indistinguishable - 5. General actuator malfunction.
If a system fault diagnosis is carried out AFTER A REPAIR OPERATION which have in­
volved disconnecting the battery and/or control unit, it is necessary to:
- turn the ignition switch to the ON position,
- wait for around 30 seconds: the control unit will carry out a "self-learning" cycle,
- return the ignition key to the OFF position,
- carry out fault diagnosis as illustrated and described previously.
