AFDZP0BA – VCM Zapi 2uC - User Manual
Page - 51/54
Replaced the controller.
25) NO CAN MSG 14
Cause:
No CAN message from pump controller
Troubleshooting:
Check the CAN connection on pump controller side. Verify that the pump
communicates on CAN bus
26) NO CAN MSG A
Cause:
No CAN message from the Mini Lever or Joystick
Troubleshooting:
Check the CAN connection on Mini Lever or Joystick side. Verify that the Mini
Lever or Joystick communicate on CAN bus
27) DRV SHRT A
Cause:
The driver of one of the first eight outputs is shorted.
Troubleshooting:
A) Check if there is a short or a low impedance pull-down between one of
the output and –BATT.
B) The driver circuit is damaged in the logic board, which has to be
replaced.
28) DRV OPEN A
Cause:
VCM is not able to drive of one of the first eight outputs.
Troubleshooting:
This type of fault is not related to external components; replace the logic
board.
29) DRV SHRT B
Cause:
The driver of one of the outputs NEV1,..NEV3 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.
30) DRV OPEN B
Cause:
VCM is not able to drive of one of the outputs NEV1,..NEV3 .
Troubleshooting:
This type of fault is not related to external components; replace the logic
board.
31) COIL OPEN A
Cause:
This fault appears when the no load is connected between one of the
outputs NEVP1, NEVP2….NEVP8 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.
