[12:11] Comparators Self Test (Active) status:

00: No Fault

01: Lo Cmp Test Fail

10: Hi Cmp Test Fail

11: Both Cmps Test fail

Reset events: POR, DATA READ

[10:9] Solenoid Logic BIST Status:

00: Idle

01: BIST running

10: BIST passed

11: BIST failed

Reset events: POR

[8:7] Solenoid Diag Self Test(OFF State): OFF State Diagnostic comparators have failed self-test.

Failure may be linked to wrong internal reference, stuck condition of the comparator or real fault happened on LOADx

pin (to be cross-checked with OFF state diagnostic).

Actions on set: No actions related to this bit.

Behavior: Read operation would reset bit status

00: Self Test pass

01: DIAG_LV comparator fail

10: DIAG OL comparator fail

11: Self Test fail

Reset events: POR, DATA READ

[6] Open Load (OFF State):

0: no fault

1: Open load

Reset events: POR, DATA READ

[5] Short Detection (OFF State):

0: no fault

1: Short detected
