CF-004
Fault Code CF-001, indicates that the drive motor (CF-M16) has a Short circuit.
Initial Actions
Check fuse F2 on Transformer.
Procedure
Disconnect the motor plug M16. Run the SDS again. Fault code CF-005 (Open circuit) is displayed?
Y N
Disconnect plug C.P2 from PCB "C". Check wires for Short circuit across leads, the orange wire M16 to C.P2-11
(violet) and the violet wire M16 to C.P2-4 (orange). Is there Short circuit?
Y N
Replace PCB "C".
Replace wire Harness.
Replace motor CF-M16.
CF-005
Fault Code CF-005, indicates that the drive motor (CF-M16) has an Open circuit.
Initial Actions
Check fuse F2 on Transformer.
Procedure
Disconnect the motor plug M16. Enter Service mode and start feed motor (CF-M16) in check motors. Measure between the
orange wire M16 and the violet wire M16 (PWM 36V and ground). The voltage is approximately 36 VDC?
Y N
Disconnect plug C.P2 from PCB "C". Measure between J2-4 and J2-11 (PWM 36V and ground). The voltage is
approximately 36 VDC?
Y N
Replace PCB "C".
Replace wire Harness.
Replace motor CF-M16.
CF-006
Fault Code CF-006, indicates that the drive motor (CF-M16) does not receive any displacement
pulses.
Initial Actions
Check fuse F2 on Transformer.
Enter the Service mode and select feed motor (CF-M16) in check motors.
Procedure
Disconnect the sensor plug Q29 to motor CF-M16. Measure between the red wire Q29 and the black wire Q29 (5V and Signal
ground). The voltage is approximately 5 VDC?
Y N
Disconnect plug F.P6 from PCB "F". Measure between the J6-13 and J6-22 (5V and Signal ground). The
voltage is approximately 5 VDC?
Y N
Replace PCB "F".
Replace wire harness.
Disconnect plug F.P6 from PCB "F". Check wires for Continuity / Short circuit from the white wire Q29 to F.P21-21,
the black wire Q29 to F.P22-21, the red wire Q29 to F.P13-21. Is there Continuity and no Short circuit?
Y N
Replace wire harness.
1. Replace motor CF-M16.
2. Replace PCB "B".
