4.7 WECS Cylinder Failure
Failure Text ME manual injection cutoff cylinder #nn (ID 45)
FCM − 20 No. LED Failure ID Display
Indication #01 to #09 45 45
Cause The fuel injection is cut off manually
Procedure
⇒
For more data, see the related alarms (WECS cylinder fail)
Remark: This failure is not shown if a cylinder is cut off automatically.
Failure Text ME both CA / TDC low shift (ID 68)
FCM − 20 No. LED Failure ID Display
Indication #05 BI1 68 68
Cause The difference between the TDC pick-up (measured angle) and CA sensor #1 and CA sensor
#2 is ±2 _ .
Procedure ⇒ Do a check for an incorrect TDC offset adjustment.
⇒ Adjust to get the correct distance between the pick-up and the flywheel tooth (4 mm).
⇒ Do a check for possible crankshaft movement.
⇒ Make sure that the CAS#1 and CAS#2 are in the correct position (at TDC #1).
⇒ Do a check of the belt condition.
⇒ Do a check of the crank angle sensor offset adjustment in flexView.
⇒ Do a CAS trend in flexView.
⇒ If each of the two CAS are defective, replace a minimum of one CAS.
⇒ Adjust the offset parameter or the belt position as necessary (see the Maintenance Manual
9223 − 1).
Remark: The measured offset in flexView changes in relation to the engine speed. Do not
adjust the offset to zero at full engine speed, because this can activate this failure at higher
ASTERN revolutions.
Failure Text ME both CA / TDC low shift (ID 68)
FCM − 20 No. LED Failure ID Display
Indication #05 BI1 68 68
Cause The difference between the TDC pick-up (measured angle) and system #1 and #2 is ±2 _ .
Procedure
⇒
Do a check for an incorrect TDC offset adjustment in flexView.
⇒ Adjust to get the correct distance between the pick-up and the flywheel tooth (4 mm).
⇒
Do a check for possible crankshaft movement.
⇒ Stop the engine, then use the turning gear and do a CAS trend in flexVIew.
⇒ Make sure that each trend line for CAS#1 and CAS#2 is the same.
