Set Condition
- Condition One:
- A current too low failure is detected if the calculated pressure control solenoid feedback current is less than or equal to a calibrated value.
- A current too high failure is detected if the calculated pressure control solenoid feedback current is greater than or equal to a calibrated value.
- Condition Two:
- A current too low failure is detected if the calculated pressure control solenoid feedback current is less than or equal to a calibrated value.
- A current too high failure is detected if the calculated pressure control solenoid feedback current is greater than or equal to a calibrated value.
- Condition Three:
- A current too low failure is detected if the calculated pressure control solenoid feedback current is less than or equal to a calibrated value.
- A current too high failure is detected if the calculated pressure control solenoid feedback current is greater than or equal to a calibrated value.
- Condition Four:
- A Serial Peripheral Interface (SPI) communication failure in the SPI communication between the Central Processing Unit (CPU) and the ASIC is detected based upon the validity of the check-byte, the timing and the feedback signal of the message.
