Failure Text
ME crank angle #2 / TDC low shift (ID 67)
FCM−20 No. LED Failure ID Display
Indication #05 BI1 67 67
Cause
The difference between the TDC pick-up and the crank angle sensor #2 is ± 2.0_
The 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#2 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 #2.
Failure Text ME crank angle #2 / TDC low shift (ID 67)
FCM−20 No. LED Failure ID Display
Indication #05 BI1 67 67
Cause
The difference between the TDC pick-up and the crank angle measurement system is #2 is ±
2.0_. The 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.
⇒ Do a check of the crank angle sensor 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 injection quantity sensor #nn meas. fail. (ID 80)
FCM−20 No. LED Failure ID Display
Indication #01 to #09 InjQ 80 80
Cause Sensor signal ZT5461C to ZT5469C is less than 2 mA or more than 22 mA (failure signal is
released after 3 seconds)
Procedure ⇒ Make sure that the the cables to the related fuel quantity sensor have no damage and are
connected correctly.
⇒ Make sure that the plug is correctly engaged with the socket.
⇒ Make sure that the measurement sleeve is correctly installed on the fuel quantity piston
⇒ Make sure that the cables between the related FCM−20 and the fuel quantity sensor have no
damage and are connected correctly.
⇒ If the feedback is not stable, replace the sensor or disconnect the plug temporarily if there are
no spares available.
