The Power stage of glow plug is monitored by Hardware for electric failures. In case of a relay between ECU and Glow
plug, the failure can be caused by the relay and not by the glow plug. If there is no intelligent relay, real electric failure of
glow plug can not be detected. In the system are present a low voltage system (metal or ceramic glow plug).

The Power stage of electric Throttle Valve actuator (H-Bridge) is monitored by Hardware for electric failures.
The Power stage of electric Throttle Valve actuator (H-Bridge) is monitored by Hardware for electric failures. The H-Bridge
has 2 switches (High side and Low side). Each circuit is monitored separately.

The Power stage of Throttle Valve actuator is monitored by Hardware for electric failures.
The Power stage of electric Throttle Valve actuator (H-Bridge) is monitored by Hardware for electric failures. The H-Bridge
has 2 switches (High side and Low side). Each circuit is monitored separately.
A plausibility check is made in case a failure ”Short circuit to Battery” (SCB) or “Short circuit to Ground” (SCG) is detected.
Therefore the switch (Low side in case of SCB , High side in case of SCG) is closed. If the Short Circuit failure disappears, it
is cleared and the Overload failure activated.

The Throttle Valve actuator gives a feedback with a position sensor. If there is a deviation between required and
measured position, the failure is activated. The system tries then to ”unblock” the actuator closing or opening it fast.
If it is not possible to “unblock” the actuator, the failure “Jammed Valve” is activated.

“To determine mechanical wearout, the Pressure Relief Valve can be forced to open by performing a defined rail pressure
shock in two steps:
- Waiting for rail pressure build up
- Performing pressure shock
The two steps are recorded in the failure memory. Pressure shock is only possible in a defined engine speed/injection
quantity range.”

For determination of the mechanical state of the pressure relief valve it is detected, if the pressure relief valve is forced to
open too many times.
The monitoring of the wear out of the PRV is done by counting the number of times the PRV is opened and the duration
of its opening. The duration of opening (PRV_tiOpn_mp) is accumulated in every driving cycle and stored in the EEPROM
in after run state of the engine. If the PRV was open for a longer time than the applied limit a failure is detected.

If rail pressure exceeds normal operation values a mechanical valve (PRV= pressure Relief Valve) is opened to control
maximum rail pressure

PRV is classified as open after the successful evaluation of the rail pressure gradients After this the rail pressure averaging
is executed continuously. If the average rail pressure is outside the expected range the open evaluation of the pressure
relief valve by rail pressure averaging failed

Euro VI and US2010 legislations require special measures to induce proper functionality of SCR and EGR systems in Heavy
Duty engines. SCR and EGR system related faults are monitored and trigger different warning and reaction.
The inducements start with a driver warning, then a torque reduction follows and if the fault is not fixed, a creep mode
with strongly reduced maximal vehicle speed is activated.
Failures which trigger inducements are grouped in 5 different categories:
- EGR Valve Blocked
- Interruption of Dosing
- Reagent Consumption
- Reagent Quality
- Tampering
The inducement logic is applied also a DPF to avoid its irreversible damage or its tampering.
