Cycle blocked after 5 attempts during the cycle or immediately if
Checks to perform:
The motor does not rotate at all
To check the wiring, measure (Ω) across
the following terminals of the circuit board
connector (fig. 35) and compare with the
correct values.
(see page 59: step 4 – motor parameters)
- across J2-6 and J2-7, the value must
be as in 4 - B (stator)
- across J2-5 and J2-6, if present, the
value must be as in step 4 - C (stator)
- across J2-5 and J2-7, the value must
be as in step 4-D (stator).
Are these values correct?
Replace the motor circuit board and
restart the diagnostic cycle to check
