P3022 MINI Description
This function will detect an error during the initialization and/or operation of a WRAF sensor controller through SPI communication. Information communicated from the Basic Software (BSW) is used for initialization and communication between Application Software (ASW) and the controller. This is used to determine if the function is working properly.
After an ECU reset, the WRAF sensor controller is started and the diagnosis determines whether the initialization has been performed in the allowed time. If not successful, then a DTC will be stored. If this is successful, then the difference is checked between the present error counter and the stored value of this error counter at ECU reset, (switching from Key
