Failure Text
ME crank angle #2 / TDC high shift (ID 64)
FCM−20 No. LED Failure ID Display
Indication #05 BI1 64 64
Cause
The difference between the TDC pick-up and the crank angle measurement system #2 is 4.0_
CA. The crank angle sensor or toothed belt has moved.
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).
⇒ 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.
Failure Text ME crank angle #1 / TDC low shift (ID 66)
FCM−20 No. LED Failure ID Display
Indication #05 BI1 66 66
Cause
The difference between the TDC pick-up and the crank angle sensor #1 is ± 2.0_
Crank angle sensor or toothed belt has moved.
Remark: No failure shown at shut-down
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 of the crank angle sensor drive.
⇒ Make sure that the CAS#1 is 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 necessary, replace CAS #1.
