The Power stage of EGR Valve actuator is monitored by Hardware for electric failures.
The Power stage of electric EGR 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 electric EGR Valve actuator (H-Bridge) is monitored by Hardware for electric failures. An overload
error is not detectable directly in case the wiring length is > 1m and the failure occurs near the actuator. Therefore 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 EGR Valve actuator gives a feedback with a position sensor. If there is a positive 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.

Hardware errors in the injectors and respective ECM power stages are investigated. Diagnostic procedure uses pattern
detection to identify specific errors and trigger appropriate substitute reaction. The behavior pattern describes in a
bit mask different detected problem (over current, command collision, RAM error,short circuit,....) when the expected
combination of errors is detected (measured and reference pattern are matching) a failure is detected. Two banks are
present.

The hardware encapsulation of CY320 performs a diagnostic of the sensor supplies and monitors the communication
Between processor and voltage supply device CY320.
A functionality for reading writing and erasing values to a memory media (Flash or EEPROM) is available.
These operations are monitored and if problems arise a failure is reported.
Communication between CJ945 (power stage chips) and CY320 (power stage voltage supplier) is monitored.
The HWE-module R2S2 is the LowLevel Chipdriver for the Powerstage-Chips R2S25200kfp.
The R2S25200 is a chip with 18 powerstages and an additional module for the monitoring of the ECU internal 5V Supply-
Voltage. It is possible to configure max. 4 R2S2.

The hardware encapsulation of CY320 performs a diagnostic of the sensor supplies and monitors the communication
Between processor and voltage supply device CY320. For reasons of safety the ECM provides 3 independent 5V voltage
supplies for the sensors. These sensor supply voltages are monitored to ensure they remain within a given range. This
check for voltage limits is done autonomously by the hardware (thresholds not applicable).
