Service Information and Procedures Class A 2385072-16-8EN
Possible Cause/Recommended Action
The is a Correlation Error. In case signals from abso-
lute coder (potentiometer) and coding wheel (motor
encoder) are not correlated.
See JC DIAG A1205 COMPRESSION CONTROL
FAILURE on page 957
Occurs when a difference is detected between the
number of steps commanded and the number of
steps detected by absolute encoder. This can hap-
pen whereas correlation is OK, for example when a
mechanical hardpoint imposes zero signal from both
encoder and potentiometer.
See JC DIAG A1206 COMPRESSION CONTROL
FAILURE on page 958
The compression speed measured by the encoder is
too high in relation to the speed profile (and correla-
tion is OK).
See JC DIAG A1206 COMPRESSION CONTROL
FAILURE on page 958
Occurs when an integrated value of the current is too
high, that is when the current is too high during too
much time.
