Failure Text
WECS cylinder lubrication passive failure. (ID 2.5)
FCM−20 No. LED Failure ID Display
Indication #03 and #04 None 125 2.5
Cause Disconnected power supply #1 or #2.
Procedure ⇒ In E85, E90 and E41.xx, make sure that the cables have no damage and are connected
correctly.
⇒ In E85, make sure that the all circuit breakers are set to on.
⇒ Repair the cables and connections in E85, E90 (terminals 40/41) and E41.xx (plug X2,
terminals 21/22).
⇒ In the FCM−20 (plug X22, terminals 55/56) of the last and last but one cylinders, make sure
that the cables and connections have no damage and are connected correctly.
⇒ Do a check of the related ALM-20 CAN−M bus indications (LED CAN 1 or CAN 2).
⇒ If the bus indications show a failure, repair the cables of the last and last but one FCM−20 (plug
X22, terminals 55/56).
⇒ Repair the cables in the related CAN−M bus. Make sure that the related ALM−20 operates.
⇒ If after all ALM−20 are started and the related ALM−20 did not start, make sure that the cable
address on the plug X1 of the related ALM-20 is connected correctly.
⇒ Do a check of the ALM-20 (plug X1, terminals 16/17) and the related resistors (see 7218-1
Resistor in plug X1, paragraph 5.2).
⇒ Repair the cables and connections in the related ALM−20.
⇒ If necessary, replace the defective ALM-20.
Failure Text ME waste heat recovery valve #1 not closed (ID 3.2.)
FCM−20 No. LED Failure ID Display
Indication #01 None 232 3.2.
Cause Waste heat recovery valve #1 (main valve) is not closed. A command to close the main valve
was sent to the valve, but the sensor responses that the valve is in the open position.
Procedure ⇒ Do a check of the position switch ZS5372C.
⇒ Make sure that the cables between the FCM-20 #01 and position switch ZS5372C have no
damage and are connected correctly.
⇒ If necessary, repair or replace the damaged cables.
⇒ If necessary, replace the position switch ZS5372C.
Failure Text ME waste heat recovery valve #1 not open (ID 3.3.)
FCM−20 No. LED Failure ID Display
Indication #05 None 233 3.3.
Cause Waste heat recovery valve #1 (main valve) is not open. A command to open the main valve
was sent to the valve, but the sensor responses that the valve is in the close position.
Procedure ⇒ Do a check of the position valve ZV7076C.
⇒ Make sure that the cables between the FCM-20 #05 and position valve ZV7076C have no
damage and are connected correctly.
⇒ If necessary, repair or replace the damaged cables.
⇒ If necessary, replace the position valve ZV7076C.
