This function checks whether the DO components operate.
When the interlock is opened while the DO test is performed, each component ends to operate.

nent is normal or not.
When all the diag. functions are stopped, all the DO components can be turned off.
DO test can make each of the DO components operate simultaneously.

enables to look for the broken or damaged parts.
Test result: NG (Go to each FIP or replace the parts.)
