Error absence ( or not detectable through the auto diagnosis).
With the key in the Pos. ON « » the CHECK LAMP remains off .
NOTE: It is possible that the problem is in the memory of the electronic control unit but could be
impossible to see it on the CHECK LAMP.
Possible Causes
CHECK LAMP wrongly connected or there is a fault in the auto diagnosis cables.
The CHECK LAMP does not work.
CHECK LAMP control
Control the CHECK LAMP (with the key inserted in the control board) through the following steps:
- Cause an intentional failure , unscrewing a sensor.
- If this failure is detected it means that the CHECK LAMP works, but the electronic control unit did not memorise
any previous fault. Therefore it is possible that a failure is present somewhere in the circuit and is not detectable
with the auto diagnosis system.
In case the CHECK LAMP does not detect the failure, control its connections and if necessary substitute it.
Failure presence
With the key in the ON « » position the CHECK LAMP does a series of flashing followed by a pause then the
code flashes that transmit every twenty seconds the error code.
The indicate the start and finish of the error code.
- Test start: is indicated by rapid flashes of on/off pulses.
- Codes: Are indicated by a series of one second duration On/Off pulses
Codice

IMPORTANT
On the IAW system 16M the phase sensor and RPM is not controlled by the electronic control unit, that
means that if there is an error it should be detected by progressive exclusion of the possible causes.
If the check of output signals (IAW 16M control system) are necessary then the motor must rotate (the action of
the starting electric motor is sufficient).
116
Every code is made up of two decimal figures separated by a pause.
These two figures indicate a defect in the sensor circuit.
- Pause
A longer pause is inserted between the first and
second number.
- End of the test: is indicated by short series of
ON/OFF pulses.
