Diagnostic Fault Check to Report the
Error Due to Non-Plausibility in ZFC
Implausible energising times. The energising times of the zero fuel
quantity calibration ZFC MoFInjDat_tiPi-
I1ZFCETCorMoFInjDat_tiPiI2ZFCETCor and MoFInjDat_tiPiI3ZFCETCor are
tested on their plausible value ranges.

11
Diagnosis Fault Check to Report the
Demand for Normal Mode Due to an
Error in the Pol2 Quantity
Implausible PoI2 efficiencies. The efficiency of PoI2 MoFMode_
facPoI2Eff_mp is tested of its plausible value range.
Or an unplausbility is detected during monitoring of the operation mode
resp. ramp time counter transgression.
14
Diagnosis Fault Check to Report the
Error to Demand for an ICO Due to an
Error in the Pol2 shut-off
Error in the PoI2 shut-off. The quantity MoFQntCor_qPoI2 is tested of its
shut-off value in normal mode.

11
Diagnosis Fault Check to Report the
Error to Demand for an ICO due to an
error in the Pol3 Efficiency Factor
Implausible PoI3 efficiencies. The efficiency of PoI3 MoFInjDat_
facPoI3EffSet is tested of its plausible value range.

Diagnostic Fault Check to Report
the Error Due to Injection Quantity
Correction
Implausible wave correction parts of the injection quantity correction. The
plausibility is displayed by the measuring points MoFQntCor_stPiI1Er-
rAct_mp MoFQntCor_stMI1ErrAct_mp and MoFQntCor_stPoI2ErrAct_mp.

Diagnostic Fault Check to Report
the Plausibility Error in Rail Pressure
Monitoring
The rail pressure of level 1 is checked after a calibratable ramp
debounce of MoFRailP_ctRmp_C (240ms) in case of a SRC error. If the
value lies outside a caliberatable window an irreversible error is detected
an reported to the DSM after an error debouncing of MoFRailP_ctDebEr-
r_C (760ms). Also in case of a rail pressure gradient error reported by the
level 1 The error is reported after a debounce time MoFRailP_ctDebGrad-
Max_C (2550ms). Additionally the error will be reported after a debounce
time MoFRailP_ctDebGradMax_C if level 2 detects a gradient error and
level 1 is not reporting it.

11
Diagnostic Fault Check to Report the
Error Due to Torque Comparison
FStSys_stStrtRlsCAN_mp = TRUE).

11
Diagnosis of Curr Path Limitation Forced
by ECU Monitoring Level 2
The setpoint path of the rail pressure control (PthLead_trqInrCurr ) is
limited by the limitation torque (EngTrqPtd_trqLim ) of the functional
control unit monitoring.
20
Diagnosis of Lead Path Limitation
Forced by ECU Monitoring Level2
The setpoint path of the air system (PthLead_trqInrLead ) is limited by
the limitation torque (EngTrqPtd_trqLim) of the functional control unit
monitoring.
21
Diagnosis of set Path Limitation Forced
by ECU Monitoring Level 2
The quantity setpoint path (PthLead_trqInrSet) is limited by the limitation
torque (EngTrqPtd_trqLim ) of the functional control unit monitoring.

Diagnostic Fault Check to Report "ABE
Active" Due to over-voltage detection
In the case of a non active shut-off path test (MoCSOP_stActMsg ==
FALSE)
whose debounce OCWDA_CTDEBSOPNOTACTV* 10ms has expired
(counter OCWDA_ctDebSOPNotActv = 0) and an active ABE wire due to
over-voltage a defect detection takes place.
4
Diagnostic Fault Check to Report "ABE
Active" due to under-voltage detection
In the case of a non active shut-off path test (MoCSOP_stActMsg ==
FALSE) whose debounce OCWDA_CTDEBSOPNOTACTV* 10ms has
expired (counter OCWDA_ctDebSOPNotActv = 0) and an active ABE wire
due to undervoltage there is an undebounced defect detection after the
battery voltage BattU_u keeps greater than OCWDA_uBattMin_C (8V)
longer than the debounce time OCWDA_CTUBATTMX(100ms).
11
Diagnostic Fault Check to Report
"WDA Active" due to Errors in Query-/
Response Communication
In the case of a non active shut-off path test (MoCSOP_stActMsg ==
FALSE) whose debounce OCWDA_CTDEBSOPNOTACTV* 10ms has
expired (counter OCWDA_ctDebSOPNotActv = 0) and an active WDA wire
a defect detection takes place.
