AFDZP0BA – VCM Zapi 2uC - User Manual
B) If, even connecting the coil to the right pin or replacing it, the alarm is still
present than the problem is inside the controller logic board, replace it.
32) COIL OPEN B
Cause:
This fault appears when the no load is connected between one of the outputs
NEV1….NEV3 and the positive.
Troubleshooting:
A) It is suggested to check the harness, in order to verify if some coil is
connected to the right connector pin and if it is not interrupted.
B) If, even connecting the coil to the right pin or replacing it, the alarm is still
present than the problem is inside the controller logic board, replace it.
33) COIL OPEN EVP9
Cause:
This fault appears when the no load is connected between one of the output
NEVP9 and the positive.
Troubleshooting:
A) It is suggested to check the harness, in order to verify if some coil is
connected to the right connector pin and if it is not interrupted.
B) If, even connecting the coil to the right pin or replacing it, the alarm is still
present than the problem is inside the controller logic board, replace it
34) DRV SHRT EVP9
Cause:
The driver of the output NEVP9 is shorted.
Troubleshooting:
A) Check if there is a short or a low impedance pull-down between one of
the outputs and –BATT.
B) The driver circuit is damaged in the logic board, which has to be
replaced.
35) DRV OPEN EVP9
Cause:
VCM is not able to drive of the output NEVP9.
Troubleshooting:
This type of fault is not related to external components; replace the logic
board.
