crank
FMI 2 – Data erratic, intermittent or incorrect
Fault code explanation: Faulty sensor / Faulty sensor circuit
Fault indication: DCU: Engine warning in DCU display.
CIU: Flash code
Flash code
Electrical fault: 2.4
Value fault: None.
Symptom: Engine is difficult to start, uses only cam sensor.

Suitable action: 1
Check the cable harness between the flywheel sensor and EMS2.
2 Check that the flywheel sensor is connected as in the circuit description.
3 Check the flywheel sensor.
FMI 3 – Voltage above normal or shorted high
(No signal)
Fault code explanation: Faulty sensor / Faulty sensor circuit
Fault indication: DCU: Engine warning in DCU display.
CIU: Flash code
Flash code
Electrical fault: 2.4
Value fault: None.
Symptom: Engine is running with imprecise timing causing risk of high fuel consumption
and smoke. Cylinder balancing not working with risk of uneven running.
Conditions for fault code: No cranksignal when expected or permanent loss of sensor signal.
Possible reason: • Open circuit in any or both of the cables to the flywheel sensor.
•
Incorrectly mounted flywheel sensor.
•
Faulty flywheel sensor.
Suitable action: 1 Check the cable harness between the flywheel sensor and EMS2.
2 Check the installation of the flywheel sensor.
3 Check the flywheel sensor.
4 Check the contact pressure in socket 37 and 38 in engine connector A.
