I am getting the hall fault in the below code which i have highlighted in red. When i run in open load the below error does not come but only in vehicle condition the fault happens.

Fault 2:
Sometimes i get the fault in
__weak bool SPD_IsMecSpeedReliable(SpeednPosFdbk_Handle_t *pHandle, const int16_t *pMecSpeedUnit)
but both faults does not come when in open load and happens only in vehicle condition. Why?
