Failure Text
WECS Modbus fail. FCM−20 #01 or #02 (ID 39)
FCM−20 No. LED Failure ID Display
Indication #01 and #02 Modbus 39 39
Cause Modbus monitoring, no communication (failure signal is released after 3 seconds).
Procedure ⇒ If the LED does not show, do a check of the cable connection in the related FCM−20 (plug X23,
terminals 63/64).
⇒ In the control boxes E90 and AMS / PCS boxes, make sure that the cables have no damage
and the connections are connected correctly.
⇒ Make sure that the modbus 120 ohm termination resistors on AMS / PCS and FCM−20 has no
damage and is connected correctly (refer to electrical drawings).
⇒ Make sure that the cables, connections and termination in the related FCM−20 and control
boxes have no damage and are connected correctly.
⇒ If the failure shows on one module only, replace the related FCM−20.
Failure Text WECS CAN S-/ SSI bus connection fail. FCM−20 #nn (ID 42)
FCM−20 No. LED Failure ID Display
Indication #00 (E90) S1 or S2 42 42
Cause Missing bus connection on CAN S-bus #1 or CAN S-bus #2 on FCM−20 #00.
Procedure ⇒ Make sure that each of the two CAN S-bus plugs X22 and X23 are correctly engaged on the
online spare FCM−20.
⇒ Make sure that the cable connection on plugs X22 and X23 on FCM−20 online spare module
is connected correctly.
⇒ For this FCM−20, set the power supply to off, then on.
⇒ Replace the FCM−20 #00 if the failure continues.
Failure Text WECS CAN S-/ SSI bus connection fail. FCM−20 #nn (ID 42)
FCM−20 No. LED Failure ID Display
Indication #01 to #08 None 42 42
Cause CAN S-bus #1 and crank angle signal #1 and/or CAN S-bus #2 and crank angle signal #2
missing on FCM−20
Procedure ⇒ Make sure that the plug X22 is correctly connected to the related FCM−20
FCM−20 No. LED Failure ID Display
Indication #01 to #07 S2 and CA2 42 42
Cause CAN S-bus #1 and crank angle signal #1 and/or CAN S-bus #2 and crank angle signal #2
missing on FCM−20
Procedure ⇒ Make sure that the plug X23 is correctly connected to the related FCM−20
