The table below presents failure modes and effects on I/O.
(a).Turning off outputs are controlled by CAN master and therefore delayed by maximum 2 bus (a).Turning off outputs are controlled by CAN master and therefore delayed by maximum 2 bus (a).Turning off outputs are controlled by CAN master and therefore delayed by maximum 2 bus (a).Turning off outputs are controlled by CAN master and therefore delayed by maximum 2 bus (a).Turning off outputs are controlled by CAN master and therefore delayed by maximum 2 bus
