FMI 9 – Abnormal update rate
Fault code explanation: EMS2 is missing the throttle signal.
Fault indication: DCU: Engine warning in DCU display.
CIU: Flash code
Flash code
Electrical fault: 2.8
Value fault: None.
Symptom: Engine goes to idle. If the accelerator is released at first and then pressed
down again the engine can be forced to run using the idle contact.
Preconditions: NOTICE! If the control panel ONLY communicates on the J1939 communi-
cation and
NOT the redundancy of J1587 for start, stop and throttle this fault
code is active in the VODIA and that is normal.
Conditions for fault code: EMS2 receives no throttle signal on the J1939 bus from the CIU.
Suitable action: 1 Check that the throttle potentiometer is connected correctly.
2 Check cable harness between CIU and the CIU throttle potentiometer.
3 Check the function of the throttle potentiometer.
