E52: No signal from the motor tachometric generator (second part)
E52
Cycle blocked after 5 attempts during the cycle or immediately if detected at the start or during
diagnostics.
E52
Tests to be performed:
To check the wiring, measure (Ω)
across the following terminals of the
circuit board connector (fig.4) and
compare with the correct values
(see page 50: step 4 – motor
parameters)
- across J7-2 and J7-5, the value must
be as in 4 - B (Stator)
- across J7-1 and J7-5, if present, the
value must be as in step 4 - D (stator ½
range)
- across J7-2 and J7-4, the value
must be as in step 4-C (rotor).
Are these values correct?
Replace the circuit board and restart
the diagnostic cycle to check for
further alarms.
Check the motor
as described on
page 50.
Is the motor OK?
The motor does not rotate at all.
NO
Replace the motor
and restart the
diagnostic cycle to
check for further
alarms.
NO
Check/replace
the wiring and
restart the
diagnostic cycle
to check for
further alarms.
If there are traces of burning on the
circuit board, refer to page 90
