Hi @jhuang1,
Which sCheck do you mean?
Refer to S32K3_SAF_SCHECK_UM.pdf
sCheck start-up
"The start-up tests override a configuration of the tested hardware modules. Configuration changes applied to the tested hardware modules may not be restored to their defaults at the end of start-up testing, therefore the user application is supposed to reconfigure the hardware modules before they can be used for user application purpose."
sCheck runtime
"These tests run with present hardware configuration of the tested module (if applicable) and always restore configuration of the tested hardware modules to the state which they have been in before the testing started."
Regards,
Daniel
